The 25 Best Seinfeld Characters Who Only Appeared In One Episode

"Seinfeld" is widely regarded as one of the greatest series of all time due to its distinctive comedic style and its memorable cast. From main players like the quick-tempered George Costanza and the oddball neighbor Kramer to supporting characters like the conniving Newman and the digression-prone Mr. Steinbrenner, there's no denying the show has one of the most remarkable collections of characters in sitcom history. By focusing on the many antics and misadventures these characters get into, "Seinfeld" quickly became one of the most popular series of its day, and continues to enjoy critical acclaim decades later. 

Given how many recurring characters fans see time and again on "Seinfeld," it's easy to forget how many smaller characters are sprinkled throughout the series. Sometimes, these characters are just as crazed and neurotic as Kramer and George. Other times, they're relatively normal people whose lives are practically ruined by their interactions with the main characters.

In many cases, these one-off characters are the highlights of the "Seinfeld" episode they appear in, proving themselves every bit as fun to watch as the main cast despite their limited screen time. Here are some of the best one-off characters to appear in the show's nine-season run.

25. Jean-Paul

Poor Jean-Paul. A competitive runner from Trinidad and Tobago, Jean-Paul appears in the Season 7 episode "The Hot Tub." Introduced as an acquaintance of Elaine's whom she met through Pendant Publishing, Jean-Paul is a world-class athlete who was set to participate in the Olympics, only to accidentally oversleep when his alarm clock malfunctioned the night before his big race.

Disappointed over this grievous mistake, Jean-Paul works hard to jumpstart his career. While training to compete in the New York Marathon, Jean-Paul is coached by Jerry, who is determined to make sure Jean-Paul doesn't oversleep as he did previously. Unfortunately, Jean-Paul's affiliation with Jerry and his friends costs Jean-Paul in the end, with Jean-Paul nearly missing the marathon (again), and scalding himself with Kramer's hot tea just as he's about to cross the finish line.

One of the many normal characters whose lives are irreversibly damaged upon meeting "Seinfeld's" main characters, Jean-Paul is the definition of someone who deserves better. Displaying a kindly attitude and generally likable personality, he just wants to cement his rightful place as one of the best runners in the world — only for Jerry and his friends to stand in the way. Additionally, it's downright adorable how quickly Jean-Paul falls in love with certain curse words he hears George say as friendly terms of endearment, innocently using them in everyday conversations without really using their true offensive meaning (to the shock and outrage of the people he talks to).

24. Milos

A man employed at the tennis pro shop that Jerry occasionally visits, Milos comes across as an expert player whose knowledge and advice can make or break a player's game. Appearing in Season 8's "The Comeback," he encourages Jerry to buy an expensive racket, claiming it's the only one he uses. Later, Jerry happens to spot Milos — disguised via large sunglasses and a baseball cap — in the middle of a tennis game, demonstrating skills that are just plain awful, with Jerry describing Milos as "the worst tennis player" he's ever seen.

Trying to keep his poor tennis playing abilities a secret, Milos at first tries to coax his wife, Patty, into sleeping with Jerry to ensure his abysmally bad playing stays under wraps. After Patty refuses to do so and loses any respect she has for Milos, Milos begs Jerry to let him win a game to "prove himself a man" in front of his wife's eyes again. When Jerry agrees, Milos pushes his luck, insulting Jerry throughout the entire game in front of a group of onlookers, causing Jerry to snap and begin creaming Milos on the court.

Milos fits right in with the overall universe of "Seinfeld": a character whose pettiness and ineptitude are his undoing. 

23. Jane

Jerry has many, many girlfriends throughout "Seinfeld," most of whom are normal, likable individuals whose relationships with Jerry are ruined based on some trivial differences between them. Every once in a while, however, Jerry meets his match when he begins dating a woman whose individual quirks and eccentric behavior exceed that of Jerry and his friends. Jane is one such example of this kind of girlfriend.

A "flinty"-voiced woman whom Jerry dates in Season 5's "The Stall," Jane's shining moment comes in a movie theater bathroom, where she refuses to give Elaine any toilet paper and tells her, "I don't have a square to spare. I can't spare a square." Jane values other disposable paper items to an extreme extent as well, selfishly clinging to any tissues and napkins she has whenever someone asks if she has any. At the end of the episode, it's also revealed that Jane secretly moonlights as Erica, a phone sex line operator whose clientele includes Kramer (who adopts the nickname Andre to hide his identity).

Jane is one of the stranger characters we've seen on the series, even by "Seinfeld" standards. Why is she so stingy with her tissues, napkins, and toilet paper? Why does she feel she can't "spare a square"? Isn't there enough toilet paper on a roll to go around? It's all these questions and more that make Jane such an intriguing one-off character, with her final comeuppance at Elaine's hands nothing short of swift, satisfying revenge.

22. Eric the Clown

Years before he was kickstarting the MCU or delivering "The Mandalorian" to "Star Wars" fans, Jon Favreau launched his career with roles on several prominent sitcoms of the 1990s, "Seinfeld" foremost among them. Appearing in Season 5's "The Fire," Favreau plays Eric the Clown, a party clown hired to entertain guests at a birthday party for the son of a woman George is dating at the time.

During the party, George gets into a heated argument with Eric due to Eric not knowing who Bozo the Clown is. Though Eric is patient and tries to engage in a reasonable discussion with George at first, he quickly tires of George's incessant ramblings, shutting him down with his impeccable delivery of the line, "You're living in the past, man. You're up on some clown from the '60s, man!" After George walks away, he notices smoke emanating from the kitchen, leading him to cause mass panic by yelling "Fire!" He then knocks down several women and children to get out of the building first. Meanwhile, the level-headed Eric stays behind, putting out the source of the fire (some overcooked burgers) with his large clown shoe before charging out in an attempt to attack George with the rest of the party guests.

An upstanding clown if ever there was one, Eric should've gotten a medal both for putting out the "fire" and for demonstrating considerable patience with George. An all-around good guy, his hilarious debate with George on Bozo has to be one of the highlights of Favreau's early work.

21. Mr. Heyman

A former high school gym teacher who instructed both Jerry and George, Mr. Heyman was one of the first archenemies George had in life. Disliking George for seemingly no reason at all, Mr. Heyman spends much of his class time mocking George and subjecting him to a wide range of humiliations, such as forcing him to smell his own gym socks and deliberately mispronouncing George's last name as "Can't-stand-ya."

He appears in Season 3's "The Library." In a flashback in that episode, he orders a group of students to give George a wedgie in the locker room. As revenge, George tells school authorities about the incident, resulting in Heyman losing his job and living without a home on the streets of New York. Years later, George recognizes an older Heyman outside of the New York Public Library. When he tries to refresh Heyman's memory about who he is, the vindictive Heyman snaps and gives George an atomic wedgie.

George has a ton of enemies in "Seinfeld," but Mr. Heyman might just be one of the worst. He's the kind of gym teacher you pray you never get, using his authority as a teacher to bully and mock his students with impunity. Still, considering the type of adult George grows into, we'd be lying if we said it wasn't a bit gratifying seeing Heyman deliver that gnarly atomic wedgie to George at the end of the episode.

20. Jimmy

A man new to Manhattan with whom Jerry, George, and Kramer occasionally play basketball, Jimmy appears in the Season 6 episode "The Jimmy." An athlete who sells his own patented shoes, Jimmy has the unusual habit of referring to himself in the third person. This habit eventually leads to confusion when Elaine tries to see whether another gym attendee is interested in her. Jimmy tells her that "Jimmy is pretty sweet on you." After clearing up the confusion, they end up agreeing to go on a date, only for it to be ruined when the irate Jimmy attacks Kramer, who cost him a potentially lucrative venture with George by accidentally breaking Jimmy's leg.

Jimmy's odd vernacular is reason enough for him to make this list. Most people only talk about themselves in the third person as a joke (Kanye excepted), but Jimmy elevates it to an art form. It's all he knows. Every single sentence out of his mouth is "Jimmy this" or "Jimmy that." The first few times you hear it, it's strange. The next few times, it's annoying. But hearing him refer to himself as Jimmy in the middle of an argument, a fight, or as he's being dragged away by security — screaming "Hands off Jimmy! Don't touch Jimmy!" — becomes downright hilarious.

Plus, it's Jimmy we have to thank for George referring to himself in the third person in later seasons — a habit he picks up here, using it to get out of work-related trouble with Steinbrenner.

19. Gino

It was a toss-up between Jerry's elderly barber, Enzo, or his far more gifted nephew, Gino, but ultimately, we decided to go with the latter instead, based on his rapport with Jerry and his excellent hair-cutting skills. Featured in Season 5's "The Barber," Jerry finds himself unhappy with his current barber, Enzo, after numerous bad haircuts. Feeling obligated to stay with him due to Enzo telling Jerry he is his most loyal customer, Jerry begins secretly seeing Gino on the side, having him fix all of Enzo's subpar haircuts.

Over time, the suspicious Enzo begins to believe Gino is seeing Jerry behind his back, confronting the two in Jerry's apartment. Just as an argument gets underway between the three men, Enzo and Gino become engrossed by "Edward Scissorhands" playing on TV — their favorite movie.

It's safe to say we've all experienced a bad haircut in our lives, each of us knowing the pain we're forced to endure until it grows back to our preferred styles or lengths. Imagine if you had someone like Gino in your corner, waiting to fix the mistake. He's the rare professional who loves and takes their craft seriously at all times. Plus, if you're ever stuck wondering what to talk about during the haircut, you can always just chat with him about Johnny Depp, one of his favorite actors.

18. Ned Isakoff

A man Elaine dates in Season 6's "The Race," Ned Isakoff is a stringent communist who suffers numerous hardships thanks to his unwavering loyalty to his beliefs. Elaine is originally thrilled with the novelty and excitement of his politics. Ned shows up throughout the episode to parody the difficulties faced by communists in America. When he finds Kramer having a hard time working at the local mall during the holiday season, Ned encourages him to read some literature on workers' rights and how they're being exploited by the upper classes, essentially converting Kramer to communism.

Later, Elaine tries to order food from a Chinese restaurant Ned's father used to frequent after being blacklisted. Problem is, Elaine previously got banned from the establishment for complaining about a botched delivery. When the driver finds out Elaine is the person behind the order, he blacklists Ned as well, claiming Elaine "named name," in a parallel to the 1950s Hollywood blacklist.

Many of Elaine's boyfriends have odd habits, but even by Elaine's standards, Ned seems exceptionally quirky. A deep believer in communism, he spends his time reading communist newspapers and ranting about the evils of capitalism to anyone who will listen. He even takes special care to look like a communist — his facial hair and glasses make him look like a mirror version of Trotsky and he dresses in drab olive clothing. He's not Elaine's best boyfriend, but he's one of the most unforgettable people she ever dated.

17. Adam Lippman

The son of Elaine's former boss, Mr. Lippman, Adam Lippman is a high-spirited young man whose bar mitzvah Elaine attends in Season 9's "The Serenity Now." As Elaine congratulates the younger Lippman on his big day, Adam quickly kisses Elaine, proclaiming himself a "man" in the process.

After the bar mitzvah has passed, the teenage lothario still tries to keep in touch with Elaine, asking her out on dates and bragging to all his friends about her. When Elaine tries to tell him how inappropriate he's being, Adam takes it the wrong way, feeling it's hypocritical to call himself a man in the eyes of the Jewish faith when Elaine tells him he's still just a boy. As a result, Adam renounces his faith, declaring that he'll never again subscribe to the teachings of Judaism.

Teenagers are a notably angsty crowd, full of hotheaded emotions and brimming with self-confidence. Adam is a perfect illustration of these two qualities. In typical teen fashion, he takes everything way too seriously, making a rash decision that will alter the course of his life based on a five-minute conversation with Elaine. Brash and impossible to reason with, he might be the best young character on "Seinfeld."  

16. Alan Mercer

Another of Elaine's more noteworthy boyfriends, Alan Mercer is a famously bad "breaker upper" whom Elaine dates a handful of times in Season 8's "The Andrea Doria." Not much is known about him, save for the fact that practically every woman he dates ends up violently hating him after Alan personally insults them when their relationship ends. After Elaine tries to break her own relationship with Alan off, Alan childishly tells her she has a big head — in the literal sense — prompting her to feel humiliated and insecure afterward.

Towards the end of the episode, the two temporarily begin dating again, with Alan apologizing for his earlier remark, only to passingly joke about a small bump in Elaine's noise. Tired of his insults, Elaine physically attacks Alan in the middle of the restaurant they're dining in, stabbing him in the head with a fork.

Alan is likely among the worst men Elaine ever dated in "Seinfeld." He's rude, immature, and overly sensitive, taking all of his breakups far more personally than need be. It's still entertaining to see him mentally break down someone like Elaine with just a simple remark. It's no wonder why he was stabbed, beaten, and had hot coffee thrown on him by his various exes with an attitude like that.

15. Ellen

Easily the best woman Jerry ever dates in the entirety of "Seinfeld," Ellen is the complete package. Making her appearance in Season 8's "The Van Buren Boys," she is kind, funny, outgoing, fun, courteous, and generally a joy to be around. She's a person anyone should feel lucky to find themselves with, having all the qualities one might look for in a significant other. The only problem is that Jerry and his friends believe she is a "loser" for some unknown reason.

While on a date with Jerry at the start of the episode, Ellen passingly mentions that it's her birthday, prompting Jerry to wonder why she didn't do anything more special with family or friends. Later, some of her friends thank Jerry for going out with her, telling him that Ellen "really needed this," making Jerry even more confused about her personal life. These incidents make Jerry search for an explanation behind Ellen's apparent lack of a social life as Kramer and George pressure him to stop dating her.

Jerry has dated many fantastic women throughout "Seinfeld," but Ellen has to be the best. She is unwaveringly nice, going out of her way to help Jerry. The fact that Jerry breaks up with her for no reason at all shows his inability to settle down. He's always looking for any pretext, no matter how trivial, to sabotage his relationships. Ellen is clearly too good for the likes of Jerry.

14. Seth

A former college buddy of Jerry's, Seth makes his appearance in Season 8's "The Chicken Roaster." Happening upon Jerry on the sidewalk, Jerry invites Seth to lunch, encouraging him to blow off a meeting at work — a decision that costs Seth his career. Now unemployed, Seth finds a job as assistant manager at the Kenny Rogers Roasters that's just opened up across from Jerry and Kramer's apartment building.

You can't help but feel bad for Seth. From the moment he appears on screen, he just can't catch a break. He seems like a great guy — cheerfully going along with Jerry, even if it means putting his own job at risk — but is completely unable to find a decent footing in life, forever getting the short end of the stick. Like so many characters the main "Seinfeld" cast encounters, his life is practically ruined not once, but twice thanks to Jerry (who's also responsible for closing Kenny Rogers Roasters by introducing rat fur into the building).

Still, no matter how grim his situation becomes, Seth always seems to have a happy-go-lucky mindset and an optimistic attitude, telling Jerry, "The important thing is we got a chance to catch up" after he's fired, dwelling on the positive aspects in life in lieu of the bad. It's a personal outlook on life we can all take a page out of.

13. Tony

Another of Elaine's many boyfriends over the years, Tony is among the most memorable of the men Elaine dates during "Seinfeld." A long-haired, sports attire-wearing, stereotypical "cool guy," he is a suave, thrill-seeking, albeit somewhat absentminded man who loves being active, and who Elaine admittedly only dates due to his looks. As she describes him to Jerry, "He's an exciting, charismatic man who just happens to have a perfect face." In Jerry's less appreciative words, Tony is a "male bimbo" (or a "mimbo," as Jerry puts it), which Elaine also admits is accurate.

Tony appears in Season 5's "The Stall," spending more time in the episode with George — who holds an unreciprocated man-crush on Tony — than he does with Elaine. The infatuated George attempts to hang out as often as possible with Tony, suggesting activities that appeal to his interests, like rock climbing. During their outing, however, Tony's face suffers a serious injury when George fails to tie a rope in place for him to climb. An upset Tony breaks off the friendship, devastating George. 

Tony wouldn't have been as great a character in "Seinfeld" if it weren't for his interactions with George. George's complete fascination with Tony, how he blushes whenever someone suggests he's in love with him, and the way he imitates Tony's mannerisms are riotously funny. It's a Ryan and Michael relationship before "The Office" was ever a thing, and for that, we can't help but thank Tony.

12. Duncan Meyer

A high school classmate of George and Jerry's, Duncan Meyer appears in Season 6's "The Race" as the boss of a woman Jerry is dating. In the episode, it's established that Duncan was Jerry's former rival, having grown obsessive over the results of a race the two had in ninth grade that Duncan (correctly) believes Jerry cheated at in order to win. Over 20 years later, Duncan is still fuming at his loss, believing himself to be faster than Jerry and continuing to insist Jerry cheated in that fateful gym class years ago.

It's always interesting to see Jerry's enemies in "Seinfeld," especially one that dates as far back as high school. While Jerry and Duncan might not have the same frosty dynamic as Jerry and Newman, Duncan still makes for a supremely entertaining one-off villain out to ruin Jerry's reputation.

The highlight of his appearance in "The Race" comes when he challenges Jerry to rematch two decades after their original race, inviting all their former classmates and even threatening to fire Jerry's girlfriend should he refuse. Of course, Jerry ends up cheating again, gaining a healthy head start on Duncan before beating him once and for all. I's more than likely Duncan will continue to fume at Jerry's victory, telling anyone who will listen Jerry cheated not once, but twice in their races together.

11. Timmy

"Seinfeld" may not have invented the act of double-dipping, but they did originate the official term for it. At the end of the day, we have the character of Timmy to personally thank for it. Appearing in Season 4's "The Implant," Timmy is the brother of a woman George is dating. The two men meet for the first time at a wake for Timmy's grandmother. Timmy spots George taking a bite out of his chip and dunking it in the dip again, to which Timmy takes offense. When Timmy tries to get George to stop and George persists, the two break out into a physical fight in the middle of the wake, causing George to be dumped and thrown out by his girlfriend and her family.

It's crazy to think such a minor character could have such a massive influence on the world at large. Timmy set an important trend, dissuading people from the unsanitary practice of double-dipping their chips in shared dips. Yes, he may be a little overzealous with how seriously he takes the whole ordeal, but it's unsung heroes of social etiquette like Timmy who are responsible for making the world a slightly cleaner, healthier place. 

10. Brody

Kramer has alluded to having a ton of friends outside the main characters of "Seinfeld" whom fans, Jerry, George, and Elaine never meet. One of the few friends Kramer fans do actually see is Brody, a shady criminal who runs an illegal bootlegging operation that produces and sells pirated films on the streets. Making his single episode appearance in Season 8's "The Little Kicks," Jerry becomes an unwitting accomplice to Brody's operation after Brody forces him to film the premiere of a film.

Impressed with Jerry's camerawork, the two begin working together more frequently, until Jerry's artistic demands grow too taxing, angering the already ill-tempered Brody. Their partnership undone, Brody physically threatens Jerry to deliver the tape of a film he was meant to shoot, then disappears once he's got the desired tape in his hands.

A guy with a very touchy side to his personality, Brody is a serious man who cares about one thing: making a buck off his films. Quick to anger, he doesn't take slights easily, threatening Jerry and Kramer repeatedly (even at gunpoint) if Jerry continues refusing to go along with his work. However, as Kramer points out, such unpredictability makes Brody a "fun" person to hang out with. We suppose it's true that there's never dull a moment when he's around.

9. Tony Abado

One of several car mechanics Jerry uses throughout "Seinfeld," Tony Abado takes the responsibilities of his job way too seriously. He's a fantastic mechanic, but people are afraid of going to him because of his love for the cars he takes care of. When Jerry takes his car to Tony in Season 7's "The Bottle Deposit," Tony chastises Jerry for his careless treatment of the car and his lack of knowledge about it, such as not knowing its exact mileage.

Pressuring Jerry to allow him to do a complete overhaul of the car's body and engine, Jerry eventually tries to get Tony to simply return the car to him as-is to take it someplace else. Threatened by the idea of losing access to such a fine vehicle, Tony steals the car for himself, disappearing into the country and ensuring the car receives the attention he feels it deserves.

Played by the predictably fantastic Brad Garrett in one of his earlier roles, Tony is one of the more standout minor characters in the "Seinfeld" universe. A man who loves his job perhaps a little too much, Tony's connection to Jerry's car borders on a love affair, with Tony stealing the car due to it being misused and ignored by Jerry. It's a silly idea, but Garrett's deadpan delivery sells the entire thing perfectly, as does his exciting chase scene with Kramer in the backwoods of Ohio.

8. Steven Koren

There have been a number of characters who seem like mirror versions of George on "Seinfeld." Possibly the most striking resemblance comes in the form of Steven Koren, a high school student who applies to the Susan Ross Scholarship in Season 8's "The Van Buren Boys." A young man who appears identical to George in personality and appearance, Steven is a mediocre student with high aspirations whom George immediately sees as a younger version of himself. As George describes it, "With a little guidance, Steven Koren is going to be everything I claim to be, only for real."

Unfortunately, when Steven changes his mind about pursuing a career as an architect — George's lifelong dream job — and opts instead to become a city planner, George revokes his scholarship, feeling betrayed by the sudden career switch. Dejected and with no other options left, Steven joins the local Van Buren Boys gang in a bid to terrorize George into changing his mind and giving him his scholarship back.

Seeing George's doppelgängers is always good for a laugh. It's all the funnier seeing George talk to a junior version of himself. It's probably good that Steven's mentor relationship with George ended when it did, considering the kind of negative effect George has on the people he grows close to.

7. Alton Benes

The parents of "Seinfeld's" main cast all pop up at one time or another, some more frequently than others. For as often as George and Jerry's parents show up in the series, it's easy to forget that Elaine's father, Alton (played by '50s tough-guy actor Lawrence Tierney) also appeared early on in the series' run, making his appearance in Season 2's "The Jacket."

A famous novelist with a surly disposition, Alton Benes meets with Elaine, Jerry, and George while visiting Manhattan, the four of them going out for a dinner on the town. Before Elaine arrives, Jerry and George endure a dry, awkward attempt at conversation with the novelist, finding little to anything in common with the overly morose Alton. He's the kind of macho writer who harkens back to Hemingway — drinking scotch on ice, dwelling on his days in the military, and brooding about his work.

Cantankerous and prone to thinking the worst about people, Alton Benes is a character we would've loved to have seen more of "Seinfeld" (just imagine his exchanges with Kramer or Frank and Estelle Costanza). According to Entertainment Weekly, the character was meant to recur on the series, but after a backstage incident involving Tierney stealing a knife from the set, the idea was vetoed. Still, at least we have this early golden episode of "Seinfeld" showing Alton in his full volatile glory.

6. Lou Filerman

Lou Filerman has to be one of the simplest but funniest joke set-ups for any character on "Seinfeld." A new employee to the J. Peterman catalog in Season 9's "The Merv Griffin Show," he is known for quickly and silently moving through the halls of the workplace, sneaking up behind people without detection, much to Elaine's annoyance. "A real sidler," as she puts it, Lou goes around surprising everyone in the office, using his speed and silent footsteps to claim credit for work he hasn't completed.

To better announce his presence, Elaine tries convincing him to carry around a pack of Tic Tacs, much the same way you'd attach a bell to a cat. The incident backfires when Peterman blames Elaine for the incessant rattling, forcing her to ditch her Tic Tac plan and find another way to track Lou.

Compared to other "Seinfeld" minor characters, Lou doesn't have many lines or even that much screen presence in the only episode he's in. He makes do with that limited appearance, flashing that huge toothy grin and popping up behind characters like a horror movie villain. It's an ingenious concept for a one-off character, making Lou one of the better employees we see at the J. Peterman workplace.

5. Henry Atkins

Kramer's quest to shut down the U.S. Postal Service in Season 9's "The Junk Mail" is quite possibly the most surreal storyline in all of "Seinfeld." Even more ridiculous than the idea behind Kramer viewing the mail as "pointless," though, is the show's depiction of the Postal Service as some kind of shadowy, secretive government organization like the CIA or NSA. When Kramer's attempts to call for the end of the Postal Service end in him being captured and detained by his local postman, he is confronted by Henry Atkins, the Postmaster General himself, played here by Wilford Brimley.

Atkins appears for less than two minutes, yet he steals the entire episode in his brief dialogue with Kramer. Initially coming across as a kindly old man, Atkins has a more sinister side to his outwardly jolly persona, threatening Kramer to cease his crusade against the Postal Service and get back to consuming his daily mail. It's a frightening transformation that seems disproportionately dramatic for the circumstances — after all, they're just talking about mail here — but Brimley's role fits in with the absurdity of the entire situation.

4. The man in the cape

Larry David can be heard throughout "Seinfeld," from recurring characters like Mr. Steinbrenner to the background voices played in numerous crowd scenes. He also has multiple on-screen cameos. One of his most underappreciated characters on "Seinfeld" has to be his role as Frank Costanza's lawyer, known only as "the man in the cape" or "the caped lawyer."

Making his brief appearance in Season 6's "The Chinese Woman," Elaine and Jerry spot the man in the cape with Frank in Manhattan. The pair wonders who the man is, why he's wearing a cape, and what Frank is doing with him (something that equally confounds George when they tell him about it). Later, Frank tells George that the man is his lawyer, explaining that he wears the cape because "[h]e's very independent. He doesn't follow the trends."

Seinfeld has had many unnamed characters during its nine-season run, but the man in the cape has to be the best. From his dramatic superhero stance while talking with Frank on the street, to the fact that he wears dark sunglasses even during the middle of the night, he's an absurd character about whom you're dying to know more. Even the fact that he introduces himself by saying "I'm Frank Costanza's lawyer" — as though his entire identity is built around being Frank's lawyer — is an ingenious concept that never stops being funny.

3. Aaron

Elaine may have had a ton of boyfriends for the years, but possibly one of the best was Aaron, AKA "the close talker" who appears in Season 5's "The Raincoats (Part 1 and Part 2)." Played by Judge Reinhold, Aaron is a kind 35-year-old man who stands far too close to people when talking to them. Elaine begins the episode believing him to be the perfect boyfriend, not noticing his odd habit. She soon becomes fed up with Aaron's bizarre obsession with Jerry's parents. Over time, Aaron begins taking such a special interest in hanging out with the Seinfelds that he starts seeing them more than he does Elaine, putting a serious strain on their relationship.

The "Seinfeld" producers could've simply gotten away with the whole "close-talker" quirk for the character, which would've been funny enough on its own. But Aaron's borderline unhealthy attachment to the Seinfelds elevates him from a one-off weirdo to a truly memorable character. 

His final meltdown at the airport alone, while bidding the Seinfelds farewell, is practically Oscar-worthy. Of course, you can't help but crack up seeing Jerry and Aaron having a conversation practically within kissing range of each other. It's great physical comedy, and it's nothing short of a crime that we didn't see Aaron more in "Seinfeld's" later seasons.

2. Gary Fogel

One of the more recognizable faces to guest star on "Seinfeld" came in Season 6's "The Scofflaw," which featured comedian Jon Lovitz playing Gary Fogel, a mutual friend of Jerry and George. At the start of the episode, George bumps into Gary, who reveals to him he is undergoing chemotherapy for cancer (something he also privately confided in Jerry months before). Later, though, Gary comes clean to George that he's actually been lying and that he never actually had cancer at all, but has been merely using the perks associated with the diagnosis — such as Jerry buying him an expensive, realistic wig — to his benefit, hiding the truth from him in the meantime.

It takes an especially horrible person to lie about having cancer. Still, Gary's inexcusable actions aren't completely that different from the main characters — George himself says he'd be probably do the same thing as Gary if it meant getting a great wig. For as awful as Gary is, he still is only slightly worse than the main characters.

Jon Lovitz has always been a great comedian to watch on any project and his comedic style meshes well with the overall tone of "Seinfeld." His ultra-confident personality, banter with George and Jerry, and over-the-top delivery of his signature catchphrase ("Good for you, Jack!") make him an incredibly entertaining addition to the "Seinfeld" universe. It's just a shame he meets his premature death off-screen via car accident after adjusting his toupee in traffic, as revealed in Season 6's "The Face Painter." 

1. Little Jerry

A lean, mean pecking machine, Little Jerry Seinfeld is a rooster purchased by Kramer in Season 8's "The Little Jerry." Originally hoping to buy a hen to supply him with farm-fresh eggs, Kramer is dismayed to learn that Little Jerry is actually a rooster, though he still takes the time to bond with and care for Little Jerry despite his egg-producing difficulties. While out on a stroll one day, Little Jerry defends himself against a dog, impressing a local bodega owner, Marcelino, who invites Kramer to participate in an illegal cockfighting tournament he runs in the back of his store. Underestimating the brutality of the competition, Kramer enrolls Little Jerry. 

To his surprise, Little Jerry performs well in the face of danger, proving himself a top-notch fighter. As he becomes more recognized in Marcelino's circle, Marcelino convinces Jerry and Kramer to rig an upcoming bout in his favor, getting Little Jerry to throw the fight. Before that can happen, Kramer steps into the ring to save Little Jerry, only to get mauled by Marcelino's own massive chicken instead.

It's funny to think the greatest minor character in "Seinfeld" isn't even human. Though he obviously doesn't have any lines or even that much screen time, Little Jerry still manages to win our hearts and minds with his amazing underdog tale, putting other up-and-coming boxing stories to shame. Deep down, we've all wanted a pet chicken at some point in our lives, and Little Jerry is the otherwise ideal companion one can have when it comes to living out that wish.
