10 Best Sheldon Cooper Episodes Of The Big Bang Theory, Ranked

Sheldon Cooper (Jim Parsons) is the heart and soul of "The Big Bang Theory" — for worse or for better, depending on how you feel about the sometimes controversial, sometimes abrasive character. Sheldon has some undeniably memorable moments throughout the show; some of them have been rather ignominious, but others have defined him as someone worth enjoying or admiring. He can be a tough nut to crack and an even tougher one to like, but that's what made him such an enduring fictional being. You might hate him, but it's hard to ignore how much of an impact he's made on the television landscape.

Whether we're talking about his connection to his best friend Leonard Hofstadter (Johnny Galecki), his nerdy proclivities, or his romantic relationship with Amy Farrah Fowler (Mayim Bialik), these 10 episodes truly capture Sheldon's essence. Here are the 10 best Sheldon Cooper episodes of "The Big Bang Theory," ranked via authorial opinion.

Sheldon's friendship with Penny (Kaley Cuoco) provide "The Big Bang Theory" with some of its best moments, and "The Adhesive Duck Deficiency" forces him to play caretaker when she hurts her shoulder while showering. It's a classic sitcom setup, but one that shows Sheldon in his most positive light — sometimes in spite of himself.

Since Sheldon and Penny are on their own because everyone else is off camping in the desert while watching the Leonid meteor shower, it distills their dynamic down to a fine point. She is sarcastic and forced to lean on him, and he is reluctantly obliging. "Let it never be said that Sheldon Lee Cooper ignored the pleas of a damsel in distress," he remarks while helping her through the arduous task of dressing and drying herself off after the accident. Eventually, he drives her to the hospital and ends up acting as her helpmeet and next of kin — all while driving her crazy and embarrassing her. It's everything the show does well about their frenemies connection, making it a wonderful episode for people who enjoy their partnership.

Sheldon and Amy's relationship follows a long and winding road that has some amazing ups and downs, but "The Fish Guts Displacement" takes everything to the next level. Amy gets sick and finds herself being pampered by Sheldon. Since her congestion requires liberal application of ointments, she finds herself faking an illness just to get some physical affection from her boyfriend. This results in an awkward spanking scene which thrills Amy and leaves Sheldon in the awkward place of playing disciplinarian.

What makes this such a solid Sheldon episode — and a good episode for the couple in general — is that it shows off their playful banter and Sheldon's reluctance toward romance. He is willing to push through his hesitancy in the name of being with his girlfriend. While they might not be as amorous on the surface as other couples on the show, "The Fish Guts Displacement" shows a pivotal point in their connection, which will only grow in future seasons.

If you've ever hummed "Soft Kitty" to yourself, you probably have this episode to thank for it. The running gag makes its debut in this outing, much to the delight of fans everywhere. Sheldon is notorious for being horribly childish when he's sick, which makes "The Pancake Batter Anomaly" such a fun ride for fans of the character. At first, he desperately avoids getting ill; then, once he's come down with his malady, he leans on Penny, who does her best to make him feel better.

Penny, naturally, is pressed into service to warble "Soft Kitty" to her friend; she also finds herself applying Vapor Rub to his chest, among other unpleasant tasks. Jim Parsons has such a good time making Sheldon the most pathetic creature in the entire universe during this episode that any fan of Sheldon's will enjoy watching him squirm and whine — and, once he feels better, try to reclaim his sense of intellectual superiority over his friends.

It's rare that Sheldon gets to spend a lot of solo time with Howard Wolowitz (Simon Helberg), but Season 7 gives him an ample chance to get to know one of his favorite targets for mockery in an up close and personal manner. Unfortunately for him, he also learns some new things about his mom, Mary (Laurie Metcalf), and how well she's getting along without his long-departed father.

Sheldon and Howard pair up for a road trip to Texas to see NASA headquarters while the rest of the gang goes to Raj's (Kunal Nayyar) murder mystery weekend in Pasadena. On the way back, they stop at Mary's home, and Sheldon witnesses his mom having a sexual encounter with a stranger. He and Howard regroup, and Sheldon tries to figure out how to confront Mary on the subject. Howard gives Sheldon a shoulder. It's a growing moment for Sheldon that's vital to his character.

"The Pants Alternative" is one of the funniest episodes in "The Big Bang Theory" history, and a real side-splitter if you're a Sheldon fan. It's a simple sitcom plot — character is too afraid to speak publicly, character consumes a substance to loosen them up, character finds themselves drunkenly flailing onstage in a moment of total public humiliation. But this is no doubt one of Jim Parsons' best Sheldon performances, adding a layer of desperate dignity to his character's reaction, which makes the entire incident an irresistible bit of comedic buffoonery.

Sheldon is slated to give a speech at the Chancellor's Awards, but he's terrified of speaking in public. At the banquet, Penny urges him to have a drink so he'll loosen up. Unfortunately, Sheldon overindulges and gives a wild, pants-free speech that soon goes viral on the internet. Whether or not it did anything to solve Sheldon's issues with public speaking is a matter of debate — especially in light of his eloquent speech at the Nobel Prize ceremony — but it's an excellent showcase for him, and for Jim Parsons' comedic skills.

Fans of "Georgie & Mandy's First Marriage" will find this episode especially satisfying — as will anyone who became very attached to Sheldon's siblings. "The Sibling Realignment" provides the viewer with yet another surprisingly vulnerably moment for Sheldon — and it also brings him a bit of closure when it comes to his fractured family relationships. If you like his character and want to get a feel for his past, this episode does a great job of that. It's a little bittersweet (and plenty funny) to see Sheldon figure out that he and his brother still have a connection in spite of their long-form fight. Coopers fight as hard as they love, and this is the ultimate proof of that.

Mary desperately wants the whole family together for Sheldon's wedding, and says she won't come unless Sheldon invites his brother, Georgie (Jerry O'Connell). Unfortunately, Sheldon and Georgie have long been estranged. Ergo, Sheldon has to go visit Georgie's automotive shop in Texas to try to convince him that he really wants him at the ceremony.

Christmas comes to Pasadena in "The Bath Item Gift Hypothesis," and Sheldon must learn how to shop for a woman that isn't his relative. It's a big step forward for the guy, and the show wrings every drop of humor out of the sight of him trying to figure out just what to get a girl like Penny.

Sheldon's answer to the dilemma of a gift exchange is to naturally go all the way over the top — he buys gift baskets that are worth varying amounts of money. He plans to convince Penny to give him her gift first, then excuse himself and grab the basket that matches the amount she's spent on him. While Leonard and Penny deal with their possibly resurgent relationship, Penny ends up giving Sheldon the ultimate gift — and he must figure out the right way to give his thanks in return. It's a classically riotous episode, with real emotion and holiday spirit thrown in.

Sheldon's longtime worship of Professor Proton (Bob Newhart) comes to a head in "The Proton Displacement," which sees Sheldon's jealousy of Leonard — a typical theme on the show — besmirch his relationship with Proton. He makes friends with Bill Nye as a form of retaliation, but Nye ends up rejecting him, and Proton and Sheldon end up teaming up for a disastrously round of revenge. Jim Parsons is hilarious when he plays Sheldon in idol worship mode, and he bounces from jealous to gleefully vengeful to utterly defeated in a matter of minutes. It's a fun one for the character and for those who want to watch Sheldon rush through a wide variety of emotions.

Professor Proton needs help finishing off a paper he's writing about nano vacuum tubes, and he turns to Leonard for help. Sheldon asks Bill Nye to be his friend and the twosome begin hanging out — stoking Proton's fury, as he hates Nye and claims that the other man stole the idea for his show from him. Unfortunately, Sheldon soon annoys Nye, too. That leads him to ultimately team up with Proton and Leonard to cause mischief — from a safe distance of 500 feet, as dictated by Nye's restraining order.

Another episode in which Sheldon meets one of his idols and suffers mightily for it, "The Excelsior Acquisition" sees Sheldon ends up behind bars — all thanks to Penny's urging. Ultimately, he gets to meet Stan Lee... and add another name to his celebrity restraining order roster. It's a roller coaster that you must ride if you want to call yourself a true Sheldon devotee.

The reason why Sheldon finds himself dealing with the legal system is because he ran a red light at Penny's behest while driving her car and trying to get her to the hospital; since she wants to avoid adding further points to her license, she blames the whole incident on him. While defending himself, Sheldon mocks the judge's position as the head of a traffic court, and then finds himself behind bars. He's ultimately forced to apologize to the judge, and Penny makes it up to Sheldon by taking him over to see Stan. A fine reward for a difficult day.

The most necessary Sheldon episode is definitely "The Einstein Approximation," if only because it contains the most hilarious use of Sheldon's signature catchphrase, "Bazinga!" It may have been introduced during "The Monopolar Expedition" in Season 2, but here, it reaches its zenith as a pop culture staple and becomes forever associated with Sheldon and his inability to land a joke properly.

It's also a great episode if you love watching Sheldon torture himself over something scientific. Here, he's trying desperately to figure out a problem with a physics question that's been bedeviling him. While electrons and their behavior haunt his thoughts, he won't sleep, which ends up keeping Leonard awake as well. When time and sleep depravation cause Sheldon to go completely unhinged, it's Leonard to the rescue — even if he has to dive into a ball pit to save him in a moment that fans of the show absolutely love to this day.
