- Caffeine Bullet Time: Fry, in the episode Three Hundred Big Boys
- Call a Human a "Meatbag": Bender's favourite insult for humans is "meatbag".
- Call Back: In the episode "The Late Philip J. Fry", at the very end, when Fry, Bender, and Farnsworth return to their own age (well, two universes later), they inadvertently crush the ones already existing in that time, provoking Farnsworth to remark "That takes care of the Time Paradox!" a reference to "Bender's Big Score," where the Time Paradox is a huge plot point.
- In the same episode, you can see various scenes from previous Futurama episodes and movies, such as Fry and That Eighties Guy entering the conference table, and Professor Farnsworth attached to Yivo.
- The best example of this was the call back to the pilot episode in the first minute of "Law and Oracle", where it starts with Fry playing a game similar to Paperboy and losing, with Zoidberg and Leela using the respective lines of the little boy and Mr. Panucci.
- In "The Silence of the Clamps", Zoidberg uses his mating head crest.
- In "All the Presidents' Heads", we get this exchange in reference to Bender's various claims throughout the 1999-2003 run of the series of the different percentage of materials that he was composed of:
Paul Revere: Ah, I see that the new scrap metal I ordered is here.
Bender: I'm 40% scrap metal, baby. (pounds on chest)
- In "Amazon Women in the Mood", Kiff refers to the accident in "A Flight To Remember" to explain when Amy gave him her number. It also shows Bender tossing away the fake heirloom from the fembot he met who died on the ship.
- In the Elephant Seal segment of "Naturama", a "beach king" Bender seal murmers in his sleep "Kill all penguins". This likely references an episode where he once posed as a penguin on Pluto and inadvertently led them to use guns.
- Though this is probably a reference to Bender's repeated uses of "kill all humans." As a seal, Bender would see penguins as the different species, hence the "kill all penguins" line.
- In the episode "Forty Percent Leadbelly", an engineer is sorting through Bender's saved files which include folders for his "Main Personality" and "Alternate Penguin Personality"
- The Scooby Doo parody segment in "Saturday Morning Fun Pit" contains a callback all the way to "Space Pilot 3000" by bringing back the drawer full of wires.
Farnsworth [Space Pilot 3000]: ...And over there is my intergalactic spaceship, and here's where I keep assorted lengths of wire. [opens drawer]
''Farnsworth [Saturday Morning Fun Pit]: ...That's my cloning machine, this is the drawer where I keep assorted lengths of wire [opens drawer], and those are the Harlem Globetrotters.
- In "Bend Her", Bender gets a sex change and pretends to be a fembot named Coilette in order to compete in the Olympics, and ends up almost marrying Calculon before faking her own death and changing back to a manbot. In "Calculon 2.0", we briefly get a look inside Calculon's suitcase; there's a photo of Coilette in the corner.
- Calvinball: Blernsball, the game that baseball has evolved into by the year 3000. It's as impossible for Fry to follow as it would be for someone from the year 1000 to understand modern baseball. Of course, the writers are actually just making stuff up.
- The Cameo: In Leela and the Genestalk the crew find Jake and Finn trapped in Mom's floating Genetics lab.
Jake: What time is it?
Bender: Time for you to shut up!
- Can-Crushing Cranium: Bender, with a whole keg.
- Cannibalism Superpower:
- Cannot Tell a Joke: Humorbot
"And I said 'Supercollider? I hardly know her.' Then they built the Supercollider. Thank you."
- Can't Get Away with Nuthin' : A very brief example of this occurs when Fry visits the abandoned ruins of Old New York and realizes he can jaywalk without fear of getting a ticket. The moment he crosses the middle of the street, he is run-over by a lizard the size of a bus which appears out of nowhere.
- Can't Live Without You: After Fry is critically injured in a car crash, his head is placed on Amy's body to keep him alive until his body is healed.
- The Caper: "Viva Mars Vegas", where the gang tries to steal the Wong's casino back from the Robot Mafia.
- Captain Obvious:
Farnsworth: Be careful with that unbreakable diamond filament!"
Bender: If it's unbreakable, why do I have to be careful?
Zoidberg: I'll save us by cutting the unbreakable diamond filament! Oh, I can't cut it.
Fry: How many atmospheres can the ship withstand?
Professor: Well it's a space ship, so I'd say between zero and one.
- Captain Space, Defender of Earth!: Zapp Brannigan.
- Cardboard Box Home: Fry asks if the homeless still use boxes to live in. Bender says yes, "but the rents are outrageous."
- Casual Interplanetary Travel: All the time. A few gags reference it, most notably in the second episode where Fry counts down to the ship launching, only to arrive when he gets to about 3.
Fry: Can I count down?
Leela: Huh? Sure.
*They take off and rapidly approach the moon as Fry counts*
Fry: Ten... nine... eight... seven...
Leela: We're here.
Fry: *quickly* Sixfivefourthreetwoone blast off!
- Casual Interstellar Travel: Distance is no barrier to plot, and our perpetually broke protagonists regularly make jaunts that are at least outside the Solar System.
- Casual Time Travel: Initially averted as the writers felt that time travel stories were difficult to make sense and didn't want the viewers to wonder why the characters didn't use it all the time; when they finally decided to do a time travel episode, "Roswell That Ends Well", they made the method of time travel an extremely rare occurrencenote to explain the latter point. However, the DVD movies and revived series have been playing this straighter, as source of time travel have been discovered to no great fanfare, although usually with some condition; "Bender's Big Score" and "The Late Philip J. Fry" both feature different types of one-way travel, and the button Farnsworth invents in "Meanwhile" is capable of taking the entire universe backwards ten seconds at a time.
- The Cast Showoff: John DiMaggio's beatboxing skills pop up a few times.
- Catch Phrase: Plenty.
"Good news, everyone!"
- His short lived catchphrase to explain why he lacked motivation to do things: "Although I am already in my pajamas."
"Bite my shiny metal ass!"
- Lampshaded by Zapp when listing Bender's most frequently used words (David Letterman Top 10 style), with "ass" being the trigger for a bomb. Of course, Bender suddenly can't remember the word "ass" to trigger it.
"Fun on a bun."
"I'm back, baby."
"Neat!" (Takes a photograph)
"Hot diggity daffodil!"
"Oy, this guy."
"I'm 40% <material under discussion>!"
"LET'S GO AL-READY!"
"I'm Scruffy...the janitor."
"I'm on break."
- Hermes has two which vary somewhat: "Great [animal] of [place or deity that rhymes with animal]!" and euphemisms involving green snakes and sugarcane. The first one is lampshaded in a scene in one episode, where Hermes is so weak from fatigue that he can only say, "Great... something, of... someplace."
- In Into the Wild Green Yonder, Hermes' wife LeBarbara attempts these a few times, to Hermes' disapproval.
Not your strong suit, woman!
"We're boned." (Shared with Bender.)
- Elzar, though it must be noted that he's an Expy of Emeril Lagasse, and the catch phrases are borrowed from him.
"Let's knock it up a notch."
- Kif's exasperated sigh.
- "I am Lrrr, ruler of the planet Omicron Persei 8!"
- Best lampshaded when he's in disguise and introduces himself as "I'm just, some guy... RULER OF THE PLANET OMICRON PERSEI 8!"
- "I'm feeling lucky!" (Used by everyone, with occasional variations)
- Fry's gotten one in the later seasons whenever he's in an accident.
- Cerebus Syndrome: Over time, Futurama went from a Science Fiction Parody to a more character driven, socio-political satire with a more darker tone and humor.
- Character Outlives Actor:
- Happens to Dr McCoy. In "Where No Fan Has Gone Before", the main cast of Star Trek: The Original Series voice themselves, except for James Doohan and DeForest Kelley. While Doohan had simply said he wasn't interested, Kelley had died. As such, Kelley's likeness appears but has no speaking lines.
- James Doohan may have been uninterested due to his suffering from Alzheimer's Disease. Terminal Red Shirt "Welshy" was created (complete with Welsh accent) to be his substitute.
- Another example: Coleene, Fry's polygamous love interest from the second movie, "Beast With A Billion Backs", who was voice by the sadly departed Brittany Murphy. In the story, Coleene was last seen fully engaged in a relationship with Yivo, the planet-sized tentacly creature from Another Dimension, which gateway was closed off by the end, sealing her status as "presumably still living there with shklim and not going to make any new appearances".
- Charity Ball: "The Mutants Are Revolting" features a charity ball for a mutant scholarship program.
- Charlie and the Chocolate Parody: In the episode "Fry And The Slurm Factory".
- Chekhov's Armoury: Although Fry's lack of a delta wave is the most prominent Chekhov's Gun, there are heaps, with some things returning in the same episode they were introduced to become something significant (e.g. the card for Leela's birthday in 6x05), to returning episodes or even seasons later to become something important (this comes to a head in the movie Bender's Big Score when everything (and everyone) introduced that may seem insignificant early on becomes absolutely essential to the plot later on).
- Chirping Crickets
- The Chosen One / The Chosen Zero: Fry. Thanks to being his own grandfather (that's time travel for you) Fry is the only sentient being in the universe who lacks a delta brain wave, thus making him immune to various forms of telepathic attack, and earning him the title of "The Mighty One" among the Nibblonians.. In the 30th century, he turns out to be the key to mankind's survival on a number of occasions, to the point that we eventually learn that Nibbler froze him on purpose in the year 2000 so he'd be alive to save the world in the 31st century.
- When Fry is told that the fate of the universe depends on him in the fourth movie, he casually replies "Yeah, I get that a lot."
- Chuck Cunningham Syndrome: Robot 1-X, who is introduced as a new Planet Express staff member in "Obsoletely Fabulous" and is gone without a trace in the next episode.
- Church of Saint Genericus: Inverted with the Amalgamated Church.
- Clark Kenting: Fry, Bender, and Leela somehow manage to pull this off in the episode "Less Than Hero."
- Cleavage Window: Many of the one-shot outfits Leela and Amy wear.
- In Leela's case, many of her one-shot outfits feature a bellybutton window instead. Probably a Shout-Out to the old prohibition on showing navels on television.
- Cliffhanger Copout: The cliffhanger of the fourth movie, in which the ship dives into a wormhole, with potential for Nothing Is the Same Anymore, was completely ruined by the Uncancelled season premiere taking the characters back to Earth immediately. Lampshade Hanging and Rule of Funny mostly make up for it.
- Clock Punk: Leonardo Da Vinci's workshop and the entire planet Vinci in the "The Duh-Vinci Code"
- Clockwork Creature: Animatronio in "The Duh-Vinci Code"
- Cloning Body Parts: Sometimes comes up in the series, such as when Fry went to "Handcrafters" after a T. rex feeding accident, or more recently when Fry and Leela each had an arm ripped off and the Professor grew them new ones.
- Closer Than They Appear: "Objects may be less sexy than they appear" shows up on a clothes shop mirror.
- Cloudcuckoolander: Fry and Zoidberg. Also Professor Farnsworth, thanks to his senility.
- Coattail-Riding Relative: Fry's initial plan in the pilot is to avoid work entirely by mooching from the Professor. He settles for low-grade employment via Nepotism instead.
- Comatose Canary
- Combat Pragmatist: Pretty much everyone, but especially Leela and Bender. Although, it is often Played for Laughs.
- Combined Energy Attack: All of the robots combining their exhaust to push the Earth out of harm's way in "Crimes of the Hot".
- Come Back to Bed, Honey: Fry hears this from his grandmother-to-be in "Roswell That Ends Well".
- Comic-Book Time: Subverted. Years actually go by and the characters comment on it, yet none of them age visibly. The show took place from 3000-3013, and Fry and Leela (for example) therefore have aged from 25 to 38, a pretty massive difference. But, their designs haven't changed at all, they don't ever mention their numerical ages, and they haven't matured too much past "20-something" behavior (or Man Child behavior, in Fry's case).
- Gets really screwy when you think about it like this; An alternate version of Fry (Lars), age 32 in 3007, aged visibly into his late 30's and 40's when he went back to the 2000's (wrinkles and matured behavior and all). Yet, now that the Fry is actually that old, he doesn't look a day over 25.
- It could simply be that, due to the better medical science of the 31st century, characters simply don't age as rapidly. For example, it's very rare for anyone nowadays to live past 110, yet the Near-Death Star in the 31st century is full of people who are 160 when admitted. The Professor himself is at least 161 before a trip to the Fountain of Aging, as shown on the age-o-meter.
- Comic Trio: The idiotic brothers Walt, Larry and Igner. They're ALL idiots, even Walt; the only reason their plans work is because they perform them on Fry.
- Compliment Backfire
- Concealing Canvas: In Bender's Big Score
- Conspicuous Gloves: Kiff: In one episode, he ends up accidentally touching Leela when his gloves come off and gets impregnated by her (his species reproduces by touch). Although the wearing of gloves is simply down to part of the uniform he and Capt. Brannigan wear.
- Conspicuously Public Assassination: The end of Bender's reign in "A Pharaoh to Remember".
- Contamination Situation: Fry has a dormant 20th C. strain of the common cold, which had been erradicated centuries earlier. It leads to the entire island of Manhattan being quarrantined and then launched to the sun for good measure.
- Context-Sensitive Button : The antennae on Bender's head seems to do everything from cooking popcorn to interrupting TV signals and it's a metaphor for a penis on top of all that.
: (finding Bender's antenna in the grass) You call that
- Continuity Nod:
- Fry's nephew was revealed to have been buried in Orbiting Meadows Cemetery in season 3's "The Luck of the Fryrish". Now, whenever a character that is important to that episode's plot or important to the main cast dies, his or her funeral is always held at Orbiting Meadows.
- Also involving Orbiting Meadows: During Fry's funeral in The Sting, an Amazonian woman is sad at Fry's death stating "him make good snoo-snoo." Cut to a shot of a row of Fry's ex-girlfriends: Lisa from the 20th century, the "dirty-boy" bureaucrat, the girl from the club that talked about when "the cyborgs ruled" and even the "radiator woman" from the "radiator planet". They all give a so-so gesture at the Amazonian's statement, indicating his average performance.
- Cosmic Ray's Pizza was used as a throwaway gag in season one's "A Fishful of Dollars." Now, it's the common place for the Planet Express crew to order or eat out.
- All four films that comprise Season 5 contain a number of nods to previous episodes, arguably to the point of Continuity Porn.
- The best nod was probably Lucy Liu's brief reappearance in Bender's body cabinet in "Love and Rocket", several episodes after he'd put her there at the end of "I Dated a Robot".
- Early in the series Professor Farnsworth mentions that they renamed Uranus "Urectum" to finally put an end to that stupid joke. In "In-A-Gadda-Da-Leela" when they zoom in on the Death Sphere, the caption on the planet where Uranus is reads Urectum.
- Richard Nixon's election as the President of Earth seems like the kind of that would be undone by a Snap Back, but he's still there.
- The Harlem Globetrotters were introduced as an alien race that wanted to ruin Earth's reputation by utterly humiliating them in a basketball game and ultimately helping the Planet Express crew solve the episode's major conflict in "Time Keeps On Slippin'". Now, whenever there's a crisis that's too big, even for Farnsworth to solve, the Globetrotters (primarily Ethan "Bubblegum" Tate) step in to save the day. Tate is also seen as a dean at Mars University in "That Darn Katz!"
- In "Lethal Inspection", Bender notes he was "in Italy last week", a nod to the previous week's episode.
- Poodles were established as extinct, however at least two have appeared in Series 6, a reference to "The Wild Green Yonder" where all extinct species were brought back.
- "The Late Philip J. Fry" is full of these, since Fry, Bender, and the Professor, travel through all of recorded history. The best example could be that time is indeed cyclical. Also, it recounts the first millennium that passed when Fry got frozen, including the fall of the original New York City, its reemergence as a medieval kingdom (and its destruction), before the emergence of New New York.
- In "The Mutants Are Revolting" As Fry leaves the Land Titanic, you can see a case of anchovies in the bottom right corner, a nod to "A Fishful of Dollars."
- In "Bender's Big Score," you can briefly see the fossilized remains of Seymour on a shelf over Lars' shoulder. Might also be seen as Foreshadowing of Lars' reveal later in the movie.
- Hermes finds another one of Fry's fossilized dogs in "A Clockwork Origin." He throws it into some soup to avoid a repeat of the last one.
- A couple more in "Ghost in the Machines," both by the Robot Devil, and within a minute of each other. The first is when he mentioned the hand-swap deal he made with Fry in the first Series Fauxnale "The Devils Hands are Idle Playthings." The second reference is when he starts singing the Robot Hell song from "Hell is Other Robots," but Bender interrupts it within the first few seconds.
- And now a major one in "Law & Oracle." Let's see what we have here: The episode starts with Fry playing an arcade game, and fails miserably. Someone says "You stink, loser" in response to his failed attempt to play an arcade game. Someone comes in with a pizza and shouts "Hey, Fry, pizza going out. Come on!" Fry takes his (hover)bike out to the Applied Cryogenics building, where he realizes he's been duped once again. These are all taken, almost from contextnote from Space Pilot 3000. He even Lampshades his tendency to not look at the customer name before making the delivery!
- The episode "All the President's Heads" features a major nod back to the third season episode "Roswell That Ends Well". In the more recent episode, the crew discovers a new method of time travel and goes back to Revolutionary days. Fry removes one of the lanterns from the "one if by land, two if by sea" church, prompting Paul Revere to exclaim "the British are coming! By land!". Upon seeing Fry's error, the Professor exclaims "Fry, you've really screwed the granny this time!".
- "All the President's Heads" also contains a nod to "Bender's Big Score". The Busty Head Doctor greets Fry at his job as a head feeder by calling him Lars. Fry tells her his real name, to which she replies, "whatever".
- "Overclockwise" shows a profile of Bender, including his full name (Bender Bending Rodriguez), serial number, and the fact that he was inspected by Inspector #5.
- Also from that episode, a sewer mutant is seen serving on the jury, a nod to them now being able to come to the surface from "The Mutants Are Revolting".
- In "A Leela of her Own", the Atlanta Braves' uniform has a trident in place of the familiar tomahawk, a nod to "The Deep South", which showed Atlanta had become an Underwater City.
- During Bender's Big Score, we see Bender fleeing after stealing an award. The chase scene involves the city being destroyed...cue the scene from the pilot of ships destroying the city outside the cryogenics lab's window.
- In "The Late Phillip J. Fry", when approaching the "present" time, scenes from previous episodes are shown (albeit re-animated), including Fry and Zoidberg dancing on a table in "A Taste of Freedom".
- Bender's gender-flip form in "Neutopia" is Coilette from "Bend Her".
- Several in the latest season:
- The time sphere, as well as the time code and Bender tattoo, which were last seen in the first DTV movie Bender's Big Score, reappeared as a minor plot point in "Decision 3012".
- The all-robot planet, as well as the Society of Robot Elders, from the fifth episode of the entire series "Fear of a Bot Planet", made a comeback in "Free Will Hunting", with an added layer to their society.
- While snooping on her mother and Zapp during "Zapp Dingbat", one of Leela's disguises is Lee Lemon, the male persona she assumed during "War is the H-Word".
- Continuity Porn: The current final season is, as of "Assie Come Home", filled to the brink with this trope. Listing all of the callbacks made to this point would require an entire page.
- Continuity Snarl: Averted. A Deleted Scene in "Bender Gets Made" features Bender crudely replacing his serial number with the number 14 to hide himself from the Robot Mafia. However, the serial number depicted was that of his good twin Flexo (2716057), not Bender's (3370318) — the implication to attentive fans being that Flexo has covertly taken over Bender's life. The creators realized this wouldn't go over well with anyone and took the scene out.
- Contrived Coincidence: In "Godfellas", Bender's return to Earth is only prompted after a very lucky spin of the radio telescope's trackball and then Fry crossing his Despair Event Horizon in earshot of the microphone. Leela Lampshades this:
Leela: This is by a wide margin the least likely thing that has ever happened!
- Hermes was the one who inspected Bender at the Tijuana manufacturing plant (as revealed in "Lethal Inspection"). Years later, they both happened to end up working at Planet Express.
- Subverted in "Fry and Leela's Big Fling": Sean's presence at Fry and Leela's vacation resort seems awfully contrived, until the reveal that it's all an arranged social experiment.
- Also played straight when the "resort" turns out to be on the same planet where the other Planet Express members are making a delivery.
- Convection Schmonvection: In The Butterfly Derby, Leela, Amy, and the Opposing Sports Team fly within inches of the molten Lava Pit in their wingsuits with no apparent ill effects.
- There's also an open Lava Pit in the basement of the Planet Express building. Every time it appears, multiple characters get extremely close to it without any discomfort.
- Conveniently Cellmates: Bender and Fry get implicated in a bank robbery with Roberto, a maniacal robot. Once they are imprisoned in the robot insane asylum, Fry's cellmate turns out to be... Roberto!
- Cool Old Guy: Farnsworth.
- Cooperation Gambit: In the episode "Mother's Day", Mom has set off a Robot War (with a remote control that forces all the robots in the world to rebel) because it's the anniversary of the day she was spurned by Prof. Farnsworth. Her sons try to end the uprising and make her happy by tracking down Farnsworth and getting him to get back together with her.
- Corrupt Corporate Executive: Mom.
- Farnsworth may count too, despite being one of the protagonists. After all, the Planet Express slogan is "Our crew is expendable, your package isn't!"
- Couch Gag: The tagline below the logo at the beginning of the theme song and the animation clip at its end. Some taglines:
"Painstakingly Drawn Before A Live Audience"
"As Foretold By Nostradamus"
"Psst — Big Party at Your House After the Show"
"When You See The Robot, Drink!"
"The Proud Result of Prison Labor"
"The Flames You See on the Screen Are Not Part of the Show"
"Bender's Wardrobe Provided by Robotany 500"
"For The Sophisticated Shut-In"
"Known to Cause Insanity in Lab Mice"
"Brought to You By Regretto Permanent Clown Make-Up"
"Ask Your Doctor if Futurama is Right For You"
"Press eyeballs to screen for cheap laser surgery"
"It knows what you're thinking!"
- Couldn't Find a Lighter: The first time crew encounter the sewer mutants, Fry quickly lights a makeshift torch and starts swinging it around threateningly. One of the sewer mutants casually lights a cigarette from the torch.
- Courtroom Episode: Several examples including part of the most recent movie.
Bender: Court's kind of fun when it's not my ass on the line.
- Cowboy Episode: The episode "Where the Buggalo Roam" is a Western parody set on Mars, including Martians who closely resemble American Indians.
- Cranial Processing Unit: Bender is shown more than once to be able to completely remove his head and continue to function in any way his head normally would.
- Crapsack World: Any place that has insane head of Richard Nixon as president of Earth, Zapp Brannigan as supreme commander of its military, a snooty WASP as a powerful judge, alien invasions being quite frequent, mutants living underground, a law that forces you to work or else be shot into the sun, and numerous other awful things, and you can see why suicide booths are common.
- The authors themselves have described it as being like present-day New York with the same problems/benefits of now, only more futuristic.
- Crazy Memory: Subverted and parodied, twice. In the episodes "Fry and the Slurm Factory" and "A Clockwork Origin," Professor Farnsworth is declared crazy and everything he has just said has been lunacy. In retaliation, he begins ranting and shouts "and he's my uncle" pointing to the much younger character, Fry. This is actually true, as Fry comes from the distant past and is Farnsworth's great great great great great uncle. However, nobody believes him, writing him off as nuts.
- Credits Gag: In Law&Oracle, Fry is being promoted:
Farnsworth: Executive delivery boy!
Conrad (whispering): It's a meaningless title, but it helps insecure people feel better about themselves.
Fry: I feel better about myself!
- Crippling the Competition: Bender drugs a bunch of race horses (and a jockey who caught him) so the only one he hasn't drugged will win and net him a big payoff.
- Crossover: One with The Simpsons has been confirmed for 2014, either at the end of that show's 25th season or the beginning of its 26th.
- Crouching Moron, Hidden Badass: Arguably, Nibbler, of all people. Despite his overwhelming cuteness, he is a soldier...
- Zoidberg is developing into one of these, as well. JOHN F*CKING ZOIDBERG!
- Cry Laughing: In the second episode, Bender taunts a park mascot who says that he still has his self respect, tries to laugh it off and falls into this trope.
Mascot: Hello, sir! I'm Craterface! I'm sorry, but I'm going to have to confiscate that alcohol!
Bender: Better mascots have tried. [drinks beer and shoves bottle into mascot's eye]
Mascot: At least I still have my self-respect! Hahahah...[breaks into sobbing]
- Crying Indian: Subverted. It looks as though he's crying about the litter, but it's because the Slurm can reminded him of how much he missed someone named Cynthia.
- Cryptic Background Reference: A thousand years of history have passed between the time Fry was frozen and let out, characters will often make casual references to events that occurred during that period of time much in the same way people in our time do with our own history.
Zapp: We have only one option. Protocol 62.
Nixon: Not possible, we don't have nearly enough piranhas!
Zoidberg: They're flying Manhattan into the sun! They mustn't have had enough piranhas!
- Cryptid Episode: In "Spanish Fry", Fry goes to look for Bigfoot, who appears at the end to act as a Deus ex Machina.
- Curbstomp Battle: The Neanderthals against the military, despite the military's advanced technology. Even called a "overwhelming victory" by Zapp Brannigan. See Rock Beats Laser.
- Cut Apart: "Beast With A Billion Backs" shows Brannigan's ship, the Nimbus, fighting fruitlessly against the tentacled creature while Brannigan narrates. We then find out he's piloting the ship by remote in an Applebees on earth.
- Cutaway Gag: In "The Mutants Are Revolting", the series' 100th episode, one of the ways that the mutants plan to take their revenge against the humans is by forcing the West Manhattan Sewer Line back up to the surface, prompting this exchange:
Fry: But who could bend such a huge steel pipe like that?
(scene then cuts to Bender, in a Hugh Hefner-style jacket, wearing sunglasses shaped like the number 100, throwing a wild party with every single minor character in the series)
- Cute Giant: The episode Mother's Day reveals that Farnsworth and Mom used to be in a relationship...until she tried to make his latest toy, Cutey McWhiskers, 18 feet tall with lasers, causing him to angrily proclaim, "Eighteen-foot-tall things aren't cute; you don't understand me!" and break up. Later they reconcile, Farnsworth admits they're still cute at 18 feet tall then Mom reveals that there's an even taller model and he gets angry again...at first.
- Cute Kitten: In "That Darn Katz!", everyone finds kittens adorable (except for Amy, who is allergic to cat fur). And one episode revealed that kittens give Morbo gas.
- Cuteness Proximity:
- Leela is often a victim of this, even in the presence of animals that are generally not that cute, such as the muck leech on Mars in Into the Wild Green Yonder. A muck leech who turns out to be evil.
- This is also a plot device in the episode "That Darn Katz!"
- Cypher Language: The alien languages found throughout the show can be decoded to reveal hidden messages.
