Comedies in general (and parodies in particular) often target popular genres and the conventions thereof. Of course, one of the many reasons these genres are so ripe for parody in the first place is because the conventions of them have been repeated to the point of ridiculousness by sequel after sequel after rip off after remake.
As a result, it's not uncommon for parodies of these genres to make a joke about having a sequel. Oddly enough, the movies that make these jokes rarely if ever end up actually having sequels made to them. This is probably because the jokes are inserted for the purpose of making fun of sequels, and actually creating one after that would be missing the point.
- The anime adaptation of Axis Powers Hetalia uses this as a Running Gag with the phrase "To Be Continued... maybe..."
- Panty & Stocking with Garterbelt has a bizarre ending with about 6 completely unforeseen plot twists in the last 60 seconds. This was followed by a splash screen stating "TO BE CONTINUED IN SEASON 2!" Of course, there was no Season 2 planned, and like 95% of the show it was somewhere between outright parody and just messing with the fans. (Just to up the ante of the trolling, at one point we did get a splash image showing what that hypothetical season would have looked like, and it was drawn like an action movie poster, complete with Enemy Mine.)
- Occurred in the outtake of Toy Story 2 when Stinky Pete said to the Barbie doll twins that he could get them a part in Toy Story 3 (which Barbie did play a substantial role in, 11 years later). Also just before the mentioned outtake above when Flik from A Bug's Life thought to Heimlich that they were shooting for A Bug's Life 2 what turns out wasn't, cut to Buzz Lightyear clearing the bushes.
- Very common in the films of Mel Brooks:
- Even the title of History of the World Part I implies a sequel, and they do "previews" to Part Two (including "Hitler On Ice!!!"), but it's clear they don't mean to make one.
- The rapping Greek Chorus in Robin Hood: Men in Tights jokes about reappearing in Robin Hood 2. No sequel has been announced.
- In Spaceballs, Yogurt jokes that he and Lone Starr will meet again in Spaceballs 2: The Search for More Money, as part of the movie's Running Gag about merchandising. No sequel has been made, though an animated series had a short run in the mid-2000s.
- In an interview with Clive James, Brooks denied vehemently that he would ever make Spaceballs II but might consider making Spaceballs III: The Search for Spaceballs II.
- Airplane II: The Sequel, in addition to demonstrating the trope in its own title, ended with the announcement "Coming Soon from Paramount Pictures: Airplane III" followed by William Shatner saying "Wait! That's exactly what they'll expect us to do!"
- Characters from Kevin Smith's movies will sometimes make jokes about sequels or about the type of films and the order they're made in: "No, first you do the safe picture, THEN you do the art picture, then sometimes you have to do the pay-back picture because your friend says you owe him!" Cue characters casting a glance at the camera.
- In the sports movie parody The Comebacks after winning the climactic football game and vowing to leave the sport forever, the main character is offered a job coaching basketball at "Sequel University". There have been no plans to make a sequel to The Comebacks, and considering its quality, that's probably a good thing.
- I'm Gonna Git You Sucka: During the climax, Mr. Big acknowledges that his character is an exploitation villain in a movie.
Mr. Big: I'm sorry, boys, but there ain't gonna be a sequel to this one.
- The original Jackass movie pulls out a final skit after the credits, hinting at a sequel dubbed Son of Jackass, where the now-elderly cast runs a march of death while getting maimed and killed in increasingly gory ways. While there was a sequel, it wasn't called Son of Jackass. For that matter, in the credits of Jackass 2, Bam begs, "Please, God, don't let there be a Jackass Three!" There was.
- Kung Pow! Enter the Fist spent a good deal of time at the end of the movie showing a full trailer for the sequel, made up mostly of scenes deleted from the first movie. Naturally, it didn't happen (though a sequel is currently in Development Hell).
- Mac and Me ends with a promise that "We'll be back!" Oh, no you won't.
- Chris Tucker, in an outtake from Rush Hour 2, upon seeing a bad guy plummet to his death, declares: "Damn! He ain't gonna be in Rush Hour 3!"
- An odd case involves the Scary Movie franchise. The Tag Line of the first movie was "No mercy. No shame. No sequel.", but this didn't stop a sequel from being released the very next year (with the Tag Line "We Lied"). Similarly, the Tag Line of Scary Movie 3 ("Great Trilogies Come in Threes") didn't stop a fourth ("The fourth and final chapter of the trilogy"), and fifth movie from being released.
- From Scream: "No, please don't kill me, Mr. Ghost face! I wanna be in the sequel!"
- Maggie Simpson's second (and currently last) word, spoken at the end of the credits in The Simpsons Movie, is "sequel?".
- In the British slasher spoof Unmasked Part 25 (whose very title implies this trope), several snarky comments are made throughout regarding the probability of another sequel.
- In an outtake of the original ending for Little Shop of Horrors, as Seymour is about to be devoured by Audrey II, he shouts, "The sequel! What about the sequel?!"
- The Live-Action Adaptation of Japanese anime Yatterman ends with a phony preview for "next week's episode".
- Doctor Detroit ends with the stinger "Doctor Detroit will return in Doctor Detroit 2: The Wrath of Mom."
- The final exchange of the film Geek Charming is the two protagonists, Josh and Dylan, discussing whether or not Josh should make a sequel to his documentary. Dylan vetoes it because "sequels are never as good as the original."
- The end of 22 Jump Street has an extended gag in which increasingly outlandish and lazily made (judging from the posters) sequels are presented even past 29 Jump Street until it finally stops at ∞ Jump Street.
- Die Hard 2: John McClane's anguished rant about "How can the same shit happen to the same guy twice?" must surely qualify as this trope on a meta level.
- The sequels to the viral monster campfest Sharknado are Sharknado 2: The Second One; Sharknado 3: Oh Hell No!; Sharknado: The 4th Awakens; Sharknado 5: Global Swarming; and the very aptly named The Last Sharknado: It's About Time.
- Mamma Mia! Here We Go Again might not have been an intentional example, but "Here We Go Again!" certainly summed up a lot of people's reactions to the announcement of a sequel to a decade-old Jukebox Musical that wasn't universally esteemed even by fans of the genre. They were pleasantly surprised.
- Bubba Ho Tep ends with a tease for a follow-up called Bubba Nosferatu: Curse of the She-Vampires, in true grindhouse fashion. It actually was in production, but ultimately got cancelled.
- The last line of Mitch Benn's "Macbeth (My Name Is)".
"Shakespeare": So last you hear from me all things are bein' equal.
Unless some dumb motherfucker decides to write a sequel.
- From "Weird Al" Yankovic's "Nature Trail to Hell":
No, you'll never see hideous effects like these again!
(Until we bring you "Nature Trail to Hell, Part 2".)
- The 100% completion ending of Banjo-Kazooie shows snapshots of the eponymous characters obtaining items inaccessible in the main game. When asked what they're for, Mumbo Jumbo tells them they'll have to wait for the sequel (which was made a few years later).
- Playing it straight, after defeating her in Banjo-Tooie, Gruntilda exclaims that she'll have her revenge in Banjo-Threeie (which wasn't made for nearly a decade).
- In the Game Boy Advance port of Donkey Kong Country, after the Kongs jump overboard and King K. Rool sails off, Cranky Kong the Meta Guy remarks, "Call that an ending? Looks like a cheap stunt setting up the story for the sequel!" In the Hero Mode ending, he tells Diddy, "You have really surpassed yourself! Who knows? Maybe you'll make the sequel."
- In Duke Nukem Forever, Duke meets on a dying character and merrily quips that he won't be in the sequel. He showed up again in the DLC.
- EarthBound joked about a sequel, and then it took it 11 years to actually get made. And it was Japan-Only.
- In Eternal Darkness one of the insanity effects was an advert for a sequel appearing, implying that the game was over.
- The Monkey Island games made a Running Gag out of referring to the franchise as having five games, even when there were only three or four. This became a Noodle Incident in Tales, which apparently skipped it over.
- The very last line in No More Heroes is Sylvia lampshading the bizarre ending of the game with "Too bad there won't be a sequel!" This, of course, turned out to be a lie.
- In Rayman 3: Hoodlum Havoc, Murfy leaves saying that he'll see us in Rayman 4. As of this writing, there has not been a game titled Rayman 4, or, indeed, any true sequel to Rayman 3.
- At one point in The Stinger to Kid Icarus: Uprising the final boss suggests that he may return if they make a sequel 25 years from now.
- The Developer Room ending of Chrono Trigger has one of the members of the development team ask "Do you want a Chrono Trigger sequel? YES/NO". A sequel was made sometime later, with only a few members of the original team.
- In Spyro: Year of the Dragon, if you refuse to pay Moneybags for access to the ice rink in Icy Peak:
Moneybags: What? You don't want to pay? What are you saving your money for, another sequel?
- The "Despacito 2" meme, which became popular around mid-2018 and parodies Hollywood's obsession with sequels and the public's overblown reaction to them.explanation
- The Simpsons:
- "He Loves to Fly and He D'ohs", the first episode after The Simpsons Movie ran in theaters, had Bart writing, "I will not wait 20 years to make another movie."
- "The Yellow Badge of Cowardge", aired nearly seven years after the movie had a Couch Gag where the Simpsons hold a panel along with Matt Groening at the "San Diego Comic Fest". Comic Book Guy asks if there will be another Simpsons movie. Cut back to the stage, where only Maggie remains, sucking her pacifier in confusion.
- "Kamp Krustier", a direct Sequel Episode to "Kamp Krusty" 24 seasons ago, joked about another followup called "Kamp Krustiest", 24 seasons later.
- Gravity Falls features an in-universe example in "Into the Bunker". A list of B-movies in The Stinger includes both "Help! My Mummy's a Werewolf" and "Help! My Mummy's a Werewolf 2: This Again".
- In the Phineas and Ferb episode "The Chronicles of Meap", the ending features a promo for the next Meap episode, "Meapless in Seattle". Subverted in that, due to popular demand, they actually made "Meapless in Seattle", which itself includes a promo for "Meap Me in St. Louis".
A long time ago in a studio in Burbank, California, a ragtag group of animators made a fake trailer for a Meap sequel they never intended to make. Unfortunately, everyone wanted to see that episode so the animators were forced to write it and incorporate all these seemingly unrelated scenes. I guess the joke was on them. We now present... Meapless in Seattle.
- Despite its name, the Rick and Morty episode "Vindicators 3: The Return of Worldender" is the only one of its kind, as the first two Vindicators adventures happened offscreen. Rick later says that he'll see them again in "Vindicators 4", but all of the Vindicators besides Supernova die before the end of the episode.
