Chris: But Mom, what's Dad gonna do about a job? Lois: Well Chris, you remember that episode of The Honeymooners where Ralph lost his job but at the end he didn't get it back? Peter: Oh yeah, that always bugged the crap outta me. What was up with that? [roll credits]
The other half of the plots end up with something apparently permanent happening to Ataru: getting split into two exact clones, or getting trapped in an alternate dimension, or getting his house overrun with mirror-demons, just to name a few. All of these consequences always end offscreen by the next chapter.
Itoshiki apparently dies in one episode of Sayonara, Zetsubou-Sensei and runs away after being unable to figure out if he is really himself in another. He's back next episode without explanation.
He actually is killed by his female "admirers" in the class in the middle of one episode in Zan, and is alive in the next scene. Maybe it never happened? Maybe he just got better? Does it matter?
Of course, this isSayonara Zetsubou Sensei we're talking about.
The Team Rocket trio gets this in Pokémon, arguably in every episode that ends with them blasting off again, but three notable instances early on in the series stand out: 1) Attack of the Prehistoric Pokémon in which they are last shown sealed inside a cave with the aforementioned Pokémon, who were previously implied to be aggressive predators. 2) Abra and the Psychic Showdown, in which Jessie and James are left paralyzed for the entirety of the episode after an encounter with Sabrina's doll, and 3) Viva Las Lapras, in which Team Rocket is arrested at the end, in one of the few times in the entire series (the previous time it happened had a scene where they dug out of prison). Cassidy and Butch have gone to jail several times, but it's usually stated that Giovanni springs for their release, something he's unlikely to do for Jessie and James.
Happens to Ash at one time, in a way that almost lampshades it. At the end of one episode, Ash gets accidentally turned into a Pikachu. The next episode starts just in time for the spell to wear off.
Mugen, Jin, and Fuu die in one episode of Samurai Champloo. This episode is never mentioned again and the characters are alive again in the next episode. This is never explained.
One early filler episode of Fairy Tail has Natsu, Loke, Gray, Lucy, Erza, and Happy all swap bodies, then learn they have half an hour to reverse the spell before the effects become permanent. With Levy's help they figure out how to undo the spell in the last minute, but there's only time to return Lucy and Gray to normal, and Levy accidentally swaps the whole rest of the guild while she's doing this. The episode promptly ends, and everything is back to normal the next time, in spite of them referencing it in a non-filler episode later.
The Officer Kuhou in that and later stories maybe a clone; she state herself that she doesn't know if she is the original in chapter 21 page 13.
Officer Kuhou: I remember! Am I real!? Am I a clone!?, Franken Fran: Calm down, calm down. It's all the same.
Space Dandy's first episode ends with the main heroes dying in an explosion. They're fine in the next episode, though QT questions it during the preview.
Grant Morrison's run on JLA is rather infamous for its rather extreme snapbacks. Premised on the idea of the JLA being an allegory for a pantheon of gods, it was decided that the JLA (being made up of seven of the heaviest of the heavy-hitters in the DCU; Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman, and Martian Manhunter) would only tackle huge, often literally world-shattering events. Threats included but were not limited to: an assault on Earth (okay, San Francisco) by renegade angels from Heaven, a war between two nigh-omnipotent djinn that threw the Earth and moon around like basketballs, not one but two mass invasions by White Martians, and (as a grand finale) a massive galaxy-killing superweapon that was defeated by granting temporary superpowers to THE ENTIRE POPULATION OF EARTH. The snapback from that final arc (awesome though it is) is enough to give you whiplash. The entire human race apparently suffers no consequences, societal changes or other effects from acquiring superpowers, fighting a galaxy-killing superweapon, and then losing those powers again; in fact, they never even bring it up. Not even in a "Oh, it's Batman: I sure wish I had superpowers again right now" kind of way.
The Donald Duck & Co universe is notorious for this. No matter how extreme the events in a story, they're nearly always somehow undone at the end and never referred to in any later tale. The protagonists may be run out of town, Duckburg may be the victim of a natural disaster, or astronomers may discover that behind our Moon there is a smaller moon of pure gold, but when the next story starts, all of the events have been magically undone. The most obvious example is Uncle Scrooge's money bin, which is completely destroyed countless times. Some things seem to be unalterable, though — while Scrooge may lose his money bin, the Beagle Boys never seem to be able to steal his money (except, ironically, in their very first appearance).
New Krypton introduced an entirely new status quo for the Superman franchise, with the title book being taken over by Mon-El, Nightwing and Flamebird taking over Action Comics, and a new planet full of Kryptonians being created. By the end of the event, New Krypton was destroyed, Flamebird and the new Kryptonians were all dead, and Mon-El and Nightwing were sent back into the Phantom Zone so that Superman could reclaim his two ongoing titles.
The first Transformers film has Bumblebee regaining his ability to speak. In the next two, he's again talking in sound bytes without explanation. Also, the films keep ending with a very public battle between a ton of robots that no Weirdness Censor could possibly cover up, and yet the Transformers are back to being a secret only conspiracy theorists believe in by the next film.
Averted in the third film where it is revealed that the final battle in the second film resulted in the Transformers becoming public knowledge.
Pretty much what happens to nearly every Bond Girl whether they survive or not. By the next film, Bond's moved on with no mention of the women from the last movie.
In the first Darkman film the artificial skin would break down after being exposed to light for exactly 99 minutes. In the sequel, Darkman works with another scientist and manages to create a new version of the skin which can withstand light for about half an hour longer. In the third film the time limit is again 99 minutes without explanation.
The books of Robert Rankin's Brentford Trilogy appear to follow one another, except each one contains sufficient destruction to make the next impossible.
In the Wheel of Time, a town called Hinderstap has people who go violently insane every night, savagely kill each other, and then wake up in the working in the same beds they'd woken up in previously. Damage to buildings is permanent, and anyone from outside who dies in their town becomes part of the cycle. They've tried every possible way to escape it, but every morning they still wake up in their beds.
In Memory of Light, Mat decides that this makes them excellent shock troops.
Live Action TV
Both played straight and subverted on NBC's Medium: while every episode, and indeed the entire premise of the show, is about how Alison has significant dreams, every time she wakes up from a dream and is upset, her husband Joe tells her to go back to sleep, because it was "just a dream". However, in the episode where their youngest daughter Marie requires glasses, she does indeed wear them again the next episode.
MST3K often does the Snap Back within the episode itself. One episode had Mike turned into a small, ventriloquist dummy-esque robot in the second host segment due to the effects of a wormhole the SOL was traveling through, and stayed that way until the next commercial break. Right after the break, he returns to normal with no more explanation than "I'm back!"
Of course, the most common example of a Snap Back on MST3K was Frank getting killed by Dr. Forrester. In every case, he was back in the next episode, looking none the worse for wear. When Frank left the show, Dr. F sang a touching song called "Who Will I Kill?", and in an episode of Cinematic Titanic, Frank lampshades it by saying blithely, "In my experience, you can die and then come right back in the next episode."
Star Trek: Spock steals the secret of the Romulan cloaking device, but the Federation never develops their own or learns how to counter it until the time of the next series. In a later Re Vision, it is explained that Starfleet has a treaty with the Romulans forbidding them from developing cloaking technology.
Justified in-episode by acknowledging that cloaking technology is an ongoing arms race. Spock: "Military secrets are the most fleeting of all"
Big character events, like Kirk's brother dying, or Picard recovering from Cardassian torture, or pretty much any time any new phenomenon/discovery/ technology is integral to the plot, are completely forgotten and everything is back to the status quo by next episode. Even the death of Kirk's son went completely unmentioned for two movies. The one notable exception to this would be Picard's assimilation by the Borg, which returned repeatedly to haunt him over the years.
In the original series episode "The Changeling," Uhura is mindwiped, and the last we hear of her she can only speak Swahili and is being retaught how to read. She's back to normal by the next episode.
Minor example from Voyager: In the episode "The Cloud" the replicator "fuel" is running low, which prompts the Voyager to venture into the titular cloud in hopes of siphoning materials to refill it from within. By the end of the episode they have failed to do so, but in the next one there is no attention paid to casual use of the replicator.
A strange example: "Isaac and Ishmael", the third season opener to The West Wing, was prepared as a Very Special Episode reacting to the 9/11 attacks. During the opening sequence, the actors, out of character, outright state that the episode is "a storytelling aberration", and that the audience should not try to fit it into the series Story Arc. The episode falls right in the middle of a Cliff Hanger, and series continuity proceeds directly from the preceding episode, "Two Cathedrals", to the next, "Manchester". While later episodes imply that the events of the episode are not, strictly speaking, non-canonical, they emphatically do not occur at any specific point in the series continuity.
On Saved by the Bell, Zach Morris works to understand a girl and her father who are very stand-offish in a Two-Part Episode. As it turns out, they're homeless and live in Bayside after it closes each day. There's a bit of a Tear Jerker conclusion when Zach allows both of them to live in his house...whereupon they are never seen nor mentioned by anyone again.
In the final episode of Series 1 of The IT Crowd, Jen sleeps with Moss, Roy sleeps with Moss's then-girlfriend (who also happens to look just like Roy's mother), and Richmond sleeps with the head of the company, Denholm Reynholm. Everything is back to normal at the start of Series 2.
Several character, but especially Baltar, in the new Battlestar Galactica series. Multiple early episodes end with him being convinced he is an instrument of God, while he's dismissive of the notion again at the start of the next episode.
On Seinfeld, Jerry and Elaine attempt to maintain a sexual relationship in addition to their friendship. This naturally backfires, and the end of the episode appears to be Jerry and Elaine's friendship reaching an abrupt end. By the next episode, it's like nothing ever happened.
This is due to Larry David thinking it would be the series finale. He'd always been against hooking Jerry and Elaine up, and only did it as a present to the execs on his way out. When the show was unexpectedly renewed, everyone agreed it was best to just sweep everything under the rug. That said, it is given a very brief Hand Wave in "The Pen", when Jerry's mother asks him what happens, he simply responds that it "didn't work out."
At the end of "The Airport", George is trapped on an airplane with a serial killer. In the next episode, he's back in New York alive and well (as "well" as George gets, anyway)
The end of "The Soup" has George banned from Monk's Cafe and sitting alone at Reggie's. Obviously, later episodes have him sitting back there with Jerry and the others taking about nothing, but with little to no explanation as to how.
George seemingly gave up his philosophy of always doing the opposite off-screen between seasons. He still keeps the job with the Yankees he gained as a result of this philosophy, though
On iCarly, Sam spends an episode doing a Girliness Upgrade because she's worried guys (and Pete, specifically) don't like her because she's too much of a tomboy. In the end, Sam has to give in to that tomboyish side to protect Carly from a bully. Pete and her end up walking out together because he likes a girl who can kick butt. He's never heard of again.
In the second episode of Garth Marenghi's Darkplace, after Liz goes crazy and tries to kill everyone, she is given a lobotomy to remove her Psychic Powers. The next episode, she still has her psychic abilities, like nothing happened. Not that the show strives for continuity...
On Boy Meets World, a few of the wackier Eric plotlines in the final season had endings that led to this. For example, "The Honeymooners" ends by showing him being boiled in a big soup pot by Hawaiian natives, yet he's back at home with no mention of this in the next episode.
An unusually serious example: In the The Sarah Jane Adventures episode "Mona Lisa's Revenge", K9 zaps the Mona Lisa and the Abomination back into paintings-along with himself. Next episode, everything's back to normal with no explanation.
Adam was shot in a mid season finale in Degrassi...and then he gets better by the premiere of the second half of the season and only brings it up twice (and one of these time, it was a one off line that was played for laughs).
Sinner was also shot and the only mention of it is when he wears a sling for his whole five second scene in the next episode.
An early episode of Father Ted ends with the atmosphere-sucking Father Stone being allowed to live in the Parochial House for ever. He's never mentioned or seen again in the rest of the series.
In the Dinosaurs episode "Green Card", Mr. Richfield fires all of his tree pushers because there are no more trees for them to push. Although they do get hired back at WESAYSO by the end (to build a wall to keep four-legged Dinosaurs away, as they are blamed for the bad economy), we never see the trees fully grown back. The next episode we see them at work shows them working as if they hadn't previously run out of trees.
Also, while most of the fired tree pushers get hired back, Richfield denies re-employment for Roy, who had just married Monica. We never see him get his job back (though the public changes its racism of four-legged Dinosaurs after they save the lives of those who got injurred building the wall to keep them out).
Friends: Chandler goes to Yemen to fend off Janice in "The One With All the Rugby". He is in New York in the next episode.
Considering that he didn't have any luggage or a passport, not so unlikely. He may have bought a ticket to Yemen, but it wasn't a direct flight. Assuming that he went anywhere, he flew as far as his connecting flight in Paris, which would take about six hours, then bought a ticket on the next flight back to New York. He wouldn't be allowed to leave De Gaulle airport without a passport, so he'd pay whatever it took for the next flight, get something to eat, and leave after four or five hours. He'd be gone less than a day. It's funny they never talk about it. Chandler's exploits in the Paris airport would be a good story; but that he'd be back home and over his jet lag in a week is not strange.
The Muppet Show: In one episode, the band decides to quit the show because they dislike the theme song, and during the end credits only Rowlf is in the orchestra. The band is back in the next episode as if no conflict had happened.
Also, in the episode with John Cleese, Gonzo's arm gets stretched longer after he catches a cannonball. When Gonzo asks the guest star for help, Cleese merely stretches Gonzo's other arm as well as his legs. After this Gonzo is not seen for the rest of the episode, and his condition isn't mentioned.
At the end of Mystery Case Files: Ravenhearst, you see a picture of the cleansed and cheerful Ravenhearst Manor. At the start of "Return To Ravenhearst", not only is it back to being a creepy, trash-filled house loaded with bizarre door locks, but it's been that way long enough for the local town council to have condemned the building.
In Ratchet & Clank: Size Matters it ends with Captain Quark shrinking down to action figure size, and just left like that yet in the next game, Tools of Destruction he is back to normal. Likely justified that Size Matters is an alternate continuity spin-off and isn't actually canon with the main series.
Goats used this trope to allow the comic to continue after frustrated aliens annihilated the Earth on a whim, killing or destroying everything relevant to the comic's canon. However, when the Earth conveniently returns after a week of guest comics, the characters remember everything (in the first comic after the Earth's destruction, a character asks, "Remember that time the Earth was destroyed?") making it either a lampshading or Subverted Trope, depending on how you look at it.
Penny Arcade does this a lot, but in a particularly notable storyline, one of the two protagonists accidentally kills his wife using a technique he learned from a video game, and goes on to win $20,000,000 in a lawsuit. The Snap Back is described in the protagonist's own words thusly: "Money's gone. In my grief, I paid a Mad Scientist twenty million for a cybernetic replica of my dead wife. It was my wish that it look, feel, and behave just as she did." The next panel keeps it from qualifying as the Reset Button, as said replica is simply a bucket on roller skates, and his wife does indeed return without explanation.
They almost never use continuity. Jokes and character traits, as well as characters can repeat, but they even once cancelled the final strip of a 3-part arc for fear of creating continuity. 3-part arcs are the longest anyone gets one Penny Arcade that aren't Twisp, Catsby or the Cardboard Tube Samurai.
Bob the Angry Flower is mostly a series of one-shots with very weak continuity. Since Bob is both powerful and amoral, it could be no other way. But one of the books includes a UN Field Guide to Bob and his various weapons and devices, which lampshades the lack of continuity and justifies it as the diligent efforts of the government. (Never let Bob near the button that blows up the Earth, since we barely managed to put it back together and ressurrect everybody last time.)
Subverted and lampshaded during the transition betweenThe Apple of Discord (a joke-a-day comic that had been heavy on Snap Back) to the spinoff comic, Apple Valley (an ongoing story comic with little-to-no Snap Back that grew out of Ao D) . Several characters go out drinking, only to wake up several states away from home with no idea where they are or how to get home. Thinking the 'joke' done, they wait around for the comic to return to normal, and are horrified when it doesn't and they realize they now have to walk home.
On Plus EV, Harold won a lot of money and lost it again, lost weight and gained it again... and so on.
In The Motley Two, one of these happened some time in the past, due to unknown temporal chicanery. Subverted In the effects do not go unnoticed by the general populace.
In "Makin' Babies", the main cast are turned into babies by a miscast magic spell. The episode ends with them still stuck as babies. They're adults again in the next episode, with no explanation or even acknowledgement that the baby incident happened. The series creator lampshades this with his description of the episode: "I had a canon once. It was awful."
Subverted elsewhere. In "Out With The Old Characters", Apple Bloom burns down the schoolhouse, which reappears in later episodes. The explanation comes in the next season's episode "Granny Smith Is Mean": The schoolhouse burns down again, then reappears in the very next scene. Sweetie Belle comments, "Aw, they're getting really fast at rebuilding the school."
The original Ćon Flux shorts often ended in her violent and occasionally gruesome death. In half (the pilot, 5 from second season, 2 from third season) of the episodes, the series would have her suffer some apparent terrible fate, and only one episode gives any explanation for why she was around the next episode. A fanon explanation is that the various Aeon Fluxes are clones. This is unconfirmed, Peter Chung has stated his distaste for Word of God. The supporting evidence is from one episode did feature an Aeon clone (and if you're not paying attention, you'll think there are a lot more— but the others are just women that Trevor made dress up like Aeon). Another episode (beyond the eight) features Aeon dying multiple times, each time coming back without explanation. This episode is notoriously difficult to make sense of, and in a bizarre twist, it's the only episode in the entire series which makes a reference to another episode.
Aqua Teen Hunger Force liberally uses a Snap Back at the end of every episode, whether it's really needed or not. No matter what happens, the next episode will have totally restored the players to start. Thus Carl's house still stands despite the fact it's been destroyed several times. Shake is still alive despite being killed at least three times. Frylock moves into his own apartment in one episode, declares he's never coming back (and he really means it, even refusing to be asked back), but is living at the Teens' house again in the next episode. The lack of continuity is never fully addressed, and considering the wackiness of the show, it's arguably not even a problem. A Running Gag on the show is centered around the only character who does not get a Snap Back each time, M.C. Pee Pants.
Surprisingly averted in the movie, which shows that the Aqua Teens used to have a brother made out of concentrated chicken nuggets, but was then devoured by a lion. It's never explained why HE didn't get to use the reboot button.
Chowder manages a particularly impressive Snap Back after the show basically deletes itself.
Literally every episode of Courage the Cowardly Dog. Something horrible and irreversible always happens to a member of the cast (usually Eustice), but none of these changes ever remain for longer than that episode.
Lampshaded in an episode of Family Guy; as the characters walk off, they comment that Peter has still lost his job, and he compares it to an episode of another series with a similar Snap Back, then expresses his disapproval of the notion. Roll credits. This is then subverted in the following episode, which involved both a job hunt and taking a new job. The show recycles the "Peter loses his job, gets a new one the following episode" plot, but it isn't as glaring as Recycled Scripts usually are, since in three of the episodes it's the B Plot.
Also any time an episode ended with Fred still in deep, deep trouble with Wilma.
Marital issues get worked out.
Lampshaded in the Futurama episode "When Aliens Attack." After convincing the Omicronians to stop attacking Earth with a fake 1999 TV broadcast, Fry says it's a law of television that "By the end of the episode, everything's always back exactly the way it was." The camera then shows an external shot of the building, with surrounding New New York in flames and the Statue of Liberty crumbling. Despite this, by the next episode, everything is back exactly the way it was.
Don't forget in the episode "Cryonic Woman", Fry loses his job at Planet Express. At the end he asks Farnsworth if he'll rehire him, but gets rejected. By the start of the next episode, he's back to being a delivery boy.
As the above lampshading implies,Futurama uses this trope all the time. In one episode, Bender has a doomsday bomb in his chest, which he detonates at the end of the episode ("Antiquing? KABOOM") while all the other protagonists are standing right next to him. Everything is back to normal by the next episode, and the explosion is never mentioned again, giving Big Lipped Alligator Moment a whole new meaning. Though said explosion happens literally right as the credits start rolling, and Bender has a line after the explosion, making it seem less dire.
The Grim Adventures of Billy & Mandy has a number of episodes that end like this, including (but not limited to): Mandy accidentally wishing everyone on Earth was gone except for herself; Grim, Mandy, Billy, and Irwin regressing back into babies and disappearing; Endsvile getting turned into a giant cheese pizza; all inhabitants on Earth (including Mandy) having Billy's genes and traits (big nose, egg-shaped head, dumb); Mandy's smile causing the universe to fall apart and transporting Grim, Billy, and herself to Townsvile as the Powerpuff Girls; Nergal forcing everybody in Endsvile to be his friends by way of mind control (as well as the viewer in breaking the fourth wall); and Grim, Billy, and Mandy fused together as some Tetsuo-like creature due to the Apple of Discord. No matter what though, by the next episode, everything's back to normal.
"Rhonda's Glasses" (Rhonda gets glasses; by story's end, she eventually decides on a non-geeky pair)
"Harold the Butcher" (Harold has to work at a butcher shop; by story's end, he's been appointed as an afterschool apprentice butcher), as well as every other "learned lesson" in the series.
"Mugged": Arnold learns martial arts. Where is it for the rest of the series?
(In some cases in the final season, this was easily dealt with by doing it to a lesser character, and then shoving him into the background for the rest of the series, e.g., "Chocolate Boy".)
Almost every episode of Making Fiends has ended in a Snap Back, except for web episodes 18-21.
Almost every episode of Invader Zim ended in this manner. (Like the one where Dib and Zim get turned into bologna. However, in that specific case, in another episode Dib references the situation, and how he and Zim worked together to get out of it.) As such, perhaps a better example is one in which Zim is sent hurtling into a sun.
There's a few other good examples, like the one where Dib ends up trapped in an Irken-designed cage while being beaten by a monkey, as Zim watches, and meanwhile Gaz has a robotic Dib maid (meaning Membrane will not question where Dib is.). Who could have let him out of the cage?
Or the one where Zim's brain-sucking monster attacks him, which supposedly would have killed him.
It also seemed like Zim died at the end of "The Wettening". "HELP! HELP! AAAH! I CAN'T BREEATHE! I-"
In fact, when Dib mentions the bologna incident Zim simply screams "YOU'RE MAKING IT UP!" Whether this counts as Zim being Zim or Canon Discontinuity is up to the viewer.
Heck, one episode ended with the entire company folding, and George going to work for the competition, With his boss following suit.
In Kim Possible the Non-Action Guy Ron learns ass kicking Monkey Kung Fu, but only actually uses it in a very few episodes, most of them monkey-oriented. Shego and Drakken are left Trapped in TV Land, but appear again without comment. Kim and Ron become involved with international law-enforcement organisation Global Justice, but they're usually saving the world on their own. It's not for nothing the producers said that any continuity happened by accident. When the series was renewed for a fourth season, things started to carry over a bit more.
Lampshaded in the one episode. "Aren't you a master of mystical monkey kung fu?" "Eh, it comes and goes, you know?"
At the end of the episode "Monkey Ninjas In Space", an army of monkey ninjas following a prophecy decide that Ron is their leader, and Kim and Ron are left wondering what to do about them. The monkeys are never mentioned again, and Ron being the "ultimate monkey master" actually is, but only in the Grand Finale.
Drakken's lair is always rebuilt by his next appearance; Ron's attempts to improve his popularity or social standing never stick; Kim cedes the captaincy of the cheer squad to Bonnie at the end of "Number One" but is back in the role later.
So The Drama even verges on Broad Strokes, such as rolling back Kim's learning to reject peer pressure and the hierarchy of the school "food chain", or Bonnie's Character Development to return her to her original role as Alpha Bitch.
It seems the writers wanted to do a Gainax Ending just to say they did. (The show loves to parody a lot of things, including tropes)
Happened in almost every single sketch of Monkey Dust where people are brought back to life so they can repeat the same gag in a slightly different way.
Subverted, and possibly parodied, on My Life as a Teenage Robot. In one episode, Jenny had accidentally thrown Sheldon into space with a bunch of Jenny-worshipping aliens. Several episodes later, Sheldon shows up again, but is now an old man, thanks to an apparent lifetime traveling at relativistic speeds trying to get back to Earth, and Jenny doesn't recognize him at first.
They got the time-bending effects of relativity backwards.
Happens a few times in Pinky and the Brain: for example, in one episode Brain invents a machine to make Pinky as smart as he is; his plan backfires and both of them end up reversing the process on themselves and becoming idiots. The episode simply ends with the two of them sitting in the cage, both now too stupid to operate the machine. Next episode, they are back to normal.
Everyone in the world is transformed into a yodeling Swedish giant and Pinky and the Brain shrug their shoulders and just accept it.
Everyone is transferred from the real Earth into a fake version of the Earth made out of papier-mache, and the real Earth subsequently explodes. It was a show that epitomized Negative Continuity.
At the end of some episodes of The Ren & Stimpy Show they sometimes get killed or in one particular episode they end up having to be sewn together to keep each other alive, and by the next episode everything is back to normal.
Rocket Power, "That Old Skateboard" (Sam finds an old skateboard; by story's end, Otto and Twister have had to fix it)
Common in Samurai Jack, notably so when Jack learns to "jump good" in order to fight the rather large Aku. Nothing seemed to stop Jack from slaying Aku and/or getting to the portal and they...just cut it short there! No explanation, no flashbacks, no nothing!
Made even worse when it is given a Continuity Nod in a later episode...
Sealab 2021 uses a Snap Back at the end of nearly every episode, when Sealab is destroyed.
Frequently parodied in The Simpsons. For example, the episode "The Principal and the Pauper." Also in "Homer Loves Flanders" wherein Lisa comments on the effect, playing with the Fourth Wall. And there's that ep with Bart and Lisa in 3rd grade where Skinner says: "What this episode has taught us is that there's nothing better than the status quo," and promptly puts them back in their respective grades.
Also somewhat subverted in The Movie, as the opening for the first episode of the next season shows that Springfield is still being rebuilt.
One episode, wherein Homer gets in trouble with a Las Vegas pit boss after losing Bart and held hostage, and Marge ends up in prison for selling expired prescription drugs in a yard sale. This leaves Lisa to fend for herself and Maggie, something she apparently always thought would eventually happen. The episode ends with her saying that she'll look for work in the morning.... by the following episode, everything has been resolved/never happened in the first place.
He is eventually brought back but very rarely dies and is often given very little to do.
Subverted in "Mysterion Rises". After 14 seasons, it turns out that Kenny is completely aware of every single death. And going right into a Crowning Moment Of Funny, when Kenny gets fed up with the gang and decides to just go to bed and get a good night's sleep. ... By shooting himself in the head.
Furthermore, we learn that nobody - except for his parents - ever remembers any of Kenny's deaths. Which is why nobody is ever surprised to see him alive again the next day.
"Trapper Keeper" is perhaps the only episode in which one of the boys' homes (Cartman's, in this case) is explicitly shown being destroyed. Of course, it's fully intact again in the next episode.
Taken to hell and back with the two-parter "You're Getting Old" and "Ass Burgers": the former averts it by ending on Stan giving into his new and strictly pessimistic world-view (i.e., everything literally looking and sounding like shit) and having his move out of town with his newly-divorced mother, with no sign that anything will ever be the same; then played as straight as possible at the end of the latter where Stan comes to accept that life doesn't just "go back to normal" like a sitcom and that the only way that he'll ever grow as a person is if he accepts change... followed immediately by everything snapping back!
In "Go Fund Yourself," the boys quit school to form a start-up company, and spend most of the episode telling their former classmates to "go fuck themselves." After their company inevitably fails, they're shocked to find that the expected snap back never happened, as everyone is still mad at them in the next episode.
Squidbillies, which is created by the same team who made ATHF, takes this to a whole new level. Some characters end up dying, and will reappear in the same scene just after a camera switch. It soon gets so insane to the point where the entire cast is pretty much made up of Iron Butt Monkeys
Unagi: Well, I guess we have to go back to being archenemies.
Ikura: Do we really have to?
Unagi: Yup, we do.
The Weekenders, "To Tish" (Tish's name is being used as a word; by story's end, she's "playing along")
Given it was a fad, it probably just faded.
What about every singleLooney Tunes character? They're always blowing each other up and it never lasts more than one scene. Occasionally you will see Sylvester or Wile E. Coyote covered in bandages/walking with crutches at the end, but at the start of the next episode everything is back to normal.
In the Metalocalypse episode "Tributeklok", Murderface falls out of a helicopter (which is up pretty high) into an angry mob. The next episode, he's perfectly fine. This is especially confusing considering that Charles Ofdensen, after being beaten almost to death at the end of season two, now has a scar on his face, showing that the show does have SOME continuity.
In the final season of Teen Titans, the Brotherhood of Evil recruits nearly every villain that ever appeared in the series despite the fact that some (like the Puppet King, Kardiak, and Malchior) were incapacitated the last time seen.
This has happened a few times on Jimmy Two-Shoes. Two episodes have Lucius and Sammy falling into an infinite abyss, only to be out by the next episode. Lucius also suffered a Villainous Breakdown in one episode, only to be cured in the next.
The show often does a Snap Back within the episode itself-for example, in one episode, a hairspray turns Jimmy into a giraffe, then he suddenly turns back to a human without explanation.
This happens in the Fairly OddParents all the time. Granted, in many cases the show would end if it didn't return to the Status Quo. However, it seems pretty jarring when the characters become Genre Savvy, the most notorious example being Wishology, in which Timmy Turner FINALLY begins making mature decisions without magic and concerning his fairies. He, also, uses the magic when he does have access to it in a mature way. By using this Reset Button this causes all sorts of Negative Continuity on the show's part.
Especially notable is that at least two episodes ended with Vicky in jail, and it doesn't stop her from coming back in the next episode. Considering her parents fear her, one has to wonder who bails her out.
This is another show that often does a snap back within the episode itself, like the time when Foop was cut in half, only to be cured in the next shot.
Fanboy and Chum Chum. Some episodes ended with characters being eaten by monsters, getting morphed into toasters, puppets and frogs, being blown up, sent into space, getting sucked into rips between space-time continuums, turned into talking dust, but by the next episode, everything is back to normal.
Doctor Doofenshmirtz from Phineas and Ferb is always back to normal by the start of the next episode, no matter what horrible thing has happened to him. Lampshaded in one episode where his daughter says, in response to a boy noting that Doofenshmirtz has just blasted off tied to a giant fireworks rocket, "He'll be fine. He blows up all the time."
A lot of Spliced episodes result in a Snap Back. One particularly notable episode ended with Entree dying when he falls off a cliff, his brain flies out of his head, and he gets crushed by a giant boulder. He's fine by the next episode. Other examples include:
"Stomach on Strike": Peri lives inside Entree as his heart, stomach, and brain. He's back out by the next episode.
"Clones Don't Care 'Bout Nothin' Either": Peri and Entree sail away from Keep Away Island to escape their clones. Next episode, they're back and their clones are never heard from again.
"Two-Arms Joe": Peri loses one of his arms and Joe gives him a mechanical one instead. He has his arm back by next episode.
"Walkie Talkie Spinesuckie": Entree's baby eats everyone's spines and Entree throws them in a volcano. They're all fine by the next episode.
"Bite, Shuffle and Moan" ended with a Zombie Apocalypse and everyone except Peri turning into a zombie (Which ends with Peri stuck on an 10 ft wide island with his zombified friends coming closer and closer...) somehow it just fixed itself...
"Mole-sters in the mist" dealt with Smarty Smarts shrinking everyone, so the Shrunken Peri and Entree team up with (The now equal size) tiny mole like creatures called Mole-sters to help fight back. Though at the end the Mole-sters double cross them, instead of growing the main cast back to normal, the episode ended with the Mole-sters making themselves human-sized and keeping the main cast as pets.
The cast of Drawn Together show up again in later episodes with not a single concern for what happened last time.
One episode ended with Nazis riding dinosaurs taking over the world. It's never mentioned again.
Ling-Ling once shows up to contest how irrational their constant snapping back is... minutes after he died and was eaten by his castmates.
Captain Hero decapitates himself with a sword because coming back is so easy. He then encourages kids at home to try it.
In Happy Tree Friends the characters die in every episode and yet they are alive and well in the next episode. For about 30 seconds, but still...
One of the factors of Superjail!, although sometimes you'll see continuity carried over. Examples include the season 2 finale leading into season 3's premiere, and the Mistress' hippie conversion being referenced later in that season. Most episodes tend to end in bizarre ways, or with most inmates killed off (to return again later).
Had the show not been renewed, the Mind Screw ending of the "Time-Police" two-parter would have been treated as "the end of the world". Obviously things got a little better.
"Terrorarium": The Superjail inmates and staff are left in a wasteland from the aftermath of giant bugs attacking. They then realize that they're trapped in a snowglobe... which is being thumped on by the Twins. Who are surrounded by numerous copies of themselves and all laughing.
"Dream Machine": The Twins' meddling with the Warden's Dream Machine causes reality to rupture, and the Warden to wake up in the real world (in live-action and played by Tim Harrington of the band Les Savy Fav).
"Cold-Blooded": Superjail freezes over completely, leaving the Warden to get his tongue stuck to Alice's breasts.
"Mayhem Donor": Jared gets his body shredded up and winds up having to be a Frankenstein-monster of body part grafts that the Doctor found from dead inmates. He's back to normal by the next one.
"Ghosts": Pretty much all the inmates die and become reincarnated as plants, which are then mowed down by the Warden.
"Planet Radio": Alice is mutated into a were-catbeast to do ballet fighting moves in a parody of Cats, along with several inmates... but the latter are all slaughtered by Jailbot (even Jean and Paul, who usually escape such fates). Jared also winds up crushed to death by the Twins, and Lord Stingray finds his old airship and escapes in it.
In Adventures of Sonic the Hedgehog this is usually what happens with Robotnik or his dumb-bots, however when his base is destroyed in "Robo-Ninjas", one of the last episodes, for the rest of the series it STAYS GONE, averting this.
