Futurama References You Missed

Airing from 1999 to 2013, off and on across Fox and Comedy Central, Futurama took the animation and humor style of co-creator Matt Groening's previous show, The Simpsons, and sent it into the world of tomorrow. Set in the 30th century, the show follows the adventures of Philip J. Fry, a pizza delivery boy from 1999 who falls into a cryogenic freezing pod and wakes up in the vastly different New New York City of 1,000 years in the future. He soon finds work at Planet Express, an interplanetary delivery firm started by his distant nephew Professor Farnsworth. Fry also finds his tribe in Leela, a one-eyed pilot, and Bender, a sociopathic robot.

Not only does Futurama look like The Simpsons, but every scene is similarly dense with layers upon layers of jokes and references. Here are some of the most obscure — and easy to miss — moments from the hilarious sci-fi saga.

Viewers have come to expect an ever-changing sight gag in the opening credits of primetime animated series. The Simpsons has Bart writing something different on a blackboard each week, American Dad! shows alien Roger popping up in his various disguises, the business next door to the titular restaurant on Bob's Burgers is forever different, and Futurama offers a one-liner at the bottom of its title screen. 

Some past examples include: "As seen on TV," "For external use only," and, on the 2010 episode "The Prisoner of Benda," "What happens in Cygnus X-1 stays in Cygnus X-1." That's a two-fer of a reference. First, it plays off of the long-used, universally known Las Vegas tourism slogan "What happens in Vegas, stays in Vegas," but substituting in the name of what sounds like a made-up alien planet from Futurama. Cygnus X-1 is a real thing, however. It's a stellar-mass black hole, a 700 light years-wide cosmic entity said to have formed from the collapse of a star. As black holes have tremendous gravitational pull and suck in anything that dares come near, well, what happens in Cygnus X-1 definitely stays in Cygnus X-1.

In the 2011 Futurama episode "Overclockwise," young clone Cubert Farnsworth gives Bender the robot a powerful upgrade to his operating system, "overclocking" him to the point where he gains superpowers. Speed-reading is among his new abilities, and he devours every book on the big shelf in the Planet Express conference room in a matter of seconds. Among the titles he instantly devours: Calculus, Advanced Calculus, the NNYC Phone Book, The Basketball Diaries, The Oxford English Dictionary, and Decline and Fall of the Romulon Empire, a book that's apparently about an alien race from Star Trek. 

He also puts away Wuthering Gattaca, evidently a combination of Emily Brontë's Wuthering Heights and the 1997 Ethan Hawke sci-fi movie Gattaca. Then, for just a fraction of a second, a book called How I Conquered Your Planet appears in Bender's hands — a title the guy who says "kill all humans" all the time would certainly enjoy. That's actually a real book, although an obscure, self-published one. It's a 2006 comic/sci-fi/detective novel by John Swartzwelder, a veteran staff writer for The Simpsons.

Never before has there been a character quite like Dr. John Zoidberg. A humanoid crustacean from the planet Decapod 10, he's the desperately lonely but personally off-putting Planet Express staff doctor who knows next to nothing about human anatomy and lives in the dumpster behind his place of business. He also speaks with a distinctive accent that voice actor Billy West told Comedy Central he settled on by combining impressions of two different entertainers, both of whom are almost completely forgotten to modern audiences. One of them is "marble-mouth George Jessel," a vaudeville comedian and early film star who had his own radio show in the early '50s. The other major Zoidberg component: Canadian character actor Lou Jacobi, who West says "had this almost rabbinical" quality to his voice.

When the series introduced Zoidberg's uncle in the 2001 episode "That's Lobstertainment!" writers went back to the old Hollywood well. Harold Zoid, a star from the "silent hologram era," has a name and character which riff on silent film comedian Harold Lloyd.

In the early seasons of Futurama, Leela feels alone in the universe. Not only is she unhappily single, but she believes she's an orphan and possibly the last living Cyclops. In the 2000 episode "A Bicyclops Built for Two," all her dreams look to come true when she falls in love with a man named Alcazar, who purports to be the last male Cyclops. She travels with him to their supposedly empty home planet of Cyclopia, where he lives in a castle. 

He's a lovely guy... until the morning after they sleep together. Suddenly, Alcazar — or Al, as he prefers to be called — is a selfish chauvinist pig. He demands she make him breakfast, then insults her cooking, and before long he's sitting glumly on an old couch watching TV, trading crude sex jokes and insults with a dissatisfied Leela, who has done her hair the way Al likes it — up and huge. This end result closely mirrors the premise and action of Married... with Children, the early Fox hit on which Katey Sagal (who voices Leela) starred as big-haired Peggy Bundy opposite Ed O'Neill as rude, crude Al Bundy. 

"The Route of All Evil" from 2002 is the rare Futurama episode that focuses on the kids — the tween-age offspring of Professor Farnsworth and Planet Express accountant Hermes Conrad. In this installment, Cubert Farnsworth (the Professor's know-it-all-clone) and Dwight Conrad (Hermes' laid-back son) go into business and direct competition with their dads, creating Awesome Express and scoring a lucrative contract to deliver the Daily Supernova newspaper to strange and distant points in outer space, primarily suburban-style homes perched on asteroids. 

At one point in the episode, Cubert and Dwight's dads zoom past an asteroid occupied by only an innocent-looking blond boy in a pale green outfit. The rolled-up paper strikes him right in the eye... and sends him off his home rock and spinning into the oblivion of space. "Au revoir!" he screams as he disappears. This space boy is rendered in a subtle, classical artistic way, as opposed to Futurama's usual modern, eye-popping look. That's because he's taken straight out of a 1943 children's book. That boy is the title character from The Little Prince, or Le Petit Prince, the tale by Antoine de Saint-Exupéry about a lonely little boy who lives on a tiny asteroid.

In the 2001 episode "Roswell That Ends Well," Fry microwaves a metal popcorn container on the Planet Express ship, upsetting the balance of radiation and sending the ship back in time and space, crash-landing in Roswell, New Mexico, in 1947. To return to the future, Professor Farnsworth needs microwave technology of some kind, and the microwave antenna at the local military base would work. He warns Fry that acquiring it could be tricky, as Fry's grandfather Enos works at that base, and if he killed him he'd erase his existence. Fry tries to protect his grandfather as best he can, and to prevent harm, he locks him in a house... which he doesn't realize is located on a nuclear weapon testing range. 

Such a test kills Enos almost immediately, and Fry tries to comfort Enos' fiancée, a diner waitress named Mildred... but they wind up sleeping together. Fry figures that since he didn't blink out of existence when Enos died, then Enos must not have been his grandfather. It tracks, however, that Mildred is still his grandmother, and became pregnant by a different guy, and that man was Fry. Professor Farnsworth later derisively refers to Fry as "Mr. I'm-My-Own-Grandpa," an explicit reference to "I'm My Own Grandpa," a hit novelty song by the duo Lonzo and Oscar. It's a strange tune that details the odd circumstances by which a man becomes his stepmother's stepfather, and thus, by default, his own grandpa. Oddly enough, the song was released in 1947.
