->''"But how could they be jamming us if they don't know ... if we're coming? ''[beat]'' Break off the attack! The shield is still up!"''
-->-- '''Lando Calrissian''', ''Film/ReturnOfTheJedi''

Bob has the situation under control, and is [[AsYouKnow explaining it to his partner, Alice]]. While he initially thought everything was fine and going to plan, it's only once he stops to think about it and hears himself say it aloud that he realizes how much trouble he and Alice are really in.

Essentially, a case of in-universe FridgeLogic (or FridgeHorror) catching up to the characters, can be played for laughs or drama. Can be triggered by the listening party's LetMeGetThisStraight putting a new perspective on Bob's explanation. If the character doesn't realize how screwed they are until after they're ''done'' explaining, it's DelayedOhCrap.

The OhCrap can also be simply that there ''really is'' NoTimeToExplain. Some situations go further with this, having the feared event happen directly after it's realized, which is a case of FiveSecondForeshadowing.

The PlaceboEurekaMoment is an inverse, in which the act of explaining leads to a solution rather just than a realization that there's a problem. Not to be confused with ICanExplain.

Amy realizes he said "...or dead" in a room full of dead bodies. The Doctor continues to explain until he realizes he's also in the room with dead bodies. Uh oh.
* ''That70sShow'': In one episode, Kitty drags Hyde to a jewelery store to see the ring she thinks that Red is buying for her behind her back. The jeweler shows her an engagement ring on reserve from a Mr. Forman. There's an inscription, "To Donna..."
--> '''Jeweler:''' You're a lucky woman, Donna. [...]
--> '''Kitty:''' Oh my goodness. This is from Eric to--
--> ''[She looks at Hyde in complete horror]''
* ''Series/RedDwarf'' does this in the episode "Out Of Time". The cast are going through unreality pockets, making them believe different things. One makes them believe Lister is actually a droid. A droid less advanced than Kryten, and therefore lower ranking. Kryten takes advantage of this to give him humiliating orders. Then comes this exchange:
--> '''Rimmer:''' So we just crashed through an unreality pocket?
--> '''Kryten:''' Which created a false reality making us believe... Mr... Lister was... oh my. (cue awkward silence for a few seconds)
--> '''Cat:''' You mean he's not a...
--> '''Kryten:''' No.
* ''Series/{{Sherlock}}'', the eponymous character often does after a SherlockScan.
** At the end of "A Study in Pink," when Sherlock agrees to help Lestrade figure out who killed [[spoiler: Jeff Hope]].
-->'''Sherlock''': The bullet they just dug out of the wall is from a hand gun. A kill shot over that distance from that kind of a weapon? That's a crack shot you're looking for, but not just a marksman. A fighter. His hands couldn't haven't shaken at all, so clearly he's acclimatized to violence. He didn't fire till I was in immediate danger, though, so strong moral principle. You're looking for a man probably with a history of military service, nerves of steel...\\
''[[spoiler: (Sherlock looks over at John, and realizes that he was the shooter)]]''\\
'''Sherlock''': Actually, you know what? Ignore me.\\
'''Lestrade''': Sorry?\\
'''Sherlock''': Ignore everything I just said. It's just the...the shock talking.
** In "The Blind Banker" Sherlock is looking through an apartment and talking to [[TheWatson John]] (well, sort of- John's left grumbling outside the door, can't hear a thing and might as well not be there).
-->'''John:''' You think maybe you could let me in this time? Oh for heaven's sake. Can you not keep doing this, please?
--> '''Sherlock:''' I'm not the first.
-->'''John:''' What?
-->'''Sherlock:''' Someone else has been here. Someone broke into this flat. He knocked that vase, just like I did. Size 11. He was tall. But not heavy. Long, thin fingers. Our acrobat.
-->'''John:''' What are you saying?
-->'''Sherlock:''' Why didn't he close it when he left-? *''{{beat}}''* [[EurekaMoment Stupid. Stupid. It's obvious!]] [[OhCrap Because he's still in here]].
** In John and Sherlock's Christmas party in "A Scandal in Belgravia," when Sherlock does his SherlockScan on a Christmas present that Molly brought, smugly trying to explain what was on Molly's mind when she wrapped it. Then he realizes who she brought it for.
-->'''Sherlock:''' Oh come on. Surely you've all seen the present at the top of the bag. Perfectly wrapped with a bow. All the others are slapdash at best. Must be someone special then. Shade of red echoes the lipstick. Either a subsonscious association or one that she's deliberately trying to encourage. Either way, Miss Hooper has ''love'' on her mind. The fact that she's serious about him is clear from the fact that she's giving him a gift at all. That all suggests long-term hopes, however forlorn. And that she's seeing him tonight is evident from the make-up and what she's wearing. [[KickTheDog Obviously trying to compensate for the size of her mouth and breasts.]]\\
''(Sherlock sees the tag on the present, which reads "Dearest Sherlock, Love Molly")''\\
'''Molly:''' [[MoodWhiplash You always say such horrible things.]] [[{{Tearjerker}} Every time. Every time...]]

* ''Series/StargateAtlantis'': The Team is on another planet and has found a crashed Wraith ship. Sheppard wants to know if one of the Wraith could still be alive.
-->'''Sheppard:''' I'm just thinking out loud here…
-->'''[=McKay=]:''' What?
-->'''Sheppard:''' How long do you think the Wraith could feed on all those humans back there?
-->'''[=McKay=]:''' Well, they're capable of hibernating for hundreds of years at a time, but, I mean, think about it. Ten thousand years ago was roughly the dawn of human civilization.
-->'''Sheppard:''' So there's no chance that uh—
-->'''[=McKay=]:''' No, no, no, no, no. Are you kidding? ''(beat)'' Well…maybe.
-->'''Sheppard:'''''(annoyed)'' [=McKay=].
-->'''[=McKay=]:''' No. No. No living thing could survive that long under those conditions. It's ridiculous.
-->'''Sheppard:''' Okay.
-->'''[=McKay=]:''' That would require an incredible power source capable of sustaining the stored humans in suspended animation almost the entire time.
-->'''Sheppard:''' So it's possible?
-->'''[=McKay=]:'''''(horrified)'' Oh, my God. It is possible. We've got to get out of here.
* In ''Series/HomeImprovement'', Jill has a rather lighthearted version when her sons tell her they want to be Film/TheThreeStooges for Halloween:
-->'''[=Jill=]:''' Why do you want to be the Stooges? They're obnoxious, they're always hitting each other - it just became clear.
* In ''Series/KamenRiderDragonKnight'', when Kit explains to Drew Lansing/Torque why he shouldn´t fight Grant Stanley/Camo and realizes he has been tricked, his expression is utterly priceless.
-->'''Kit:''' Torque, stop, listen. Xaxiax has been tricking the other riders, offering each one something he wants. He told Incisor he'd give him a million bucks to take out Wing Knight. This guy ''(points to Camo)'' wanted a challenge. Xaviax told him Wing Knight was the toughest man on two worlds. Everyone who's after Wing Knight... ''(realizing he has been tricked)'' is working for Xaviax...
-->'''[=Torque=]:'''''(laughs)'' Congratulations, Kit. Thank you for playing. Let's tell him what he's won... a one-way pass to the Advent Void.
* In the ''Series/{{Friends}}'' episode "The One With The Memorial Service", Chandler and Ross have been having a prank war posting bogus information on each others' college alumni webpages. This culminates with Chandler announcing Ross's death.
-->'''Ross''': Your little "Ross is dead" joke didn't work, okay? There were no responses. Nobody posted anything on the website, nobody called my parents. So the joke, my friend, is on you. Nobody called, nobody wrote anything. Nobody cares that I'm dead! ({{Beat}}). Oh my God! Nobody cares that I'm ''dead''?
* Used several times on ''Series/BuffyTheVampireSlayer''.
** In an early episode, Buffy and Xander have assumed that Willow will be targeted by a demon that wants to steal a good brain. Willow idly wonders if they should warn Giles, to which Xander responds "Don't worry about Giles, I mean he is really... smart." Cue them running out of the library.
** When the group is reconciling after the events of 'The Yoko Factor', Buffy lets the others come to their own conclusions to realize that it was Spike who played them off against one another.
-->'''Giles''': Well, Spike can be very convincing, and... we're very stupid.
** And before this in the same episode, Spike and Adam are discussing the success of Spike's plan - he has successfully separated Buffy from her friends, now they just need Buffy to work with her friend to decode the information disc. Adam points out the contradiction here. According to the episode commentary, this was actually a bit of an AuthorsSavingThrow from when they had the same realization.
-->'''Spike''': Our little witch gives her the info and pop - Alice heads back down the rabbit hole.\\
'''Adam''': The witch.\\
'''Spike''': Uh, Willow. About so high, perky, good with math. Natural choice.\\
'''Adam''': Her friend.\\
'''Spike''': Right.\\
'''Adam''': One of the friends from whom you've so efficiently separated her.\\
'''Spike''': Damn right I did. You should've seen 'em. They won't be talking to each other for a long, long... [''beat''] Hang on. I think I might have detected a small flaw.
** Glory buys supplies for a dangerous summoning from The Magic Box before Giles actually knows what she looks like - he only has Buffy's vague description of a superpowered girl. Later, when Anya is horrified to see what he sold, Giles assures her that it's no danger because "The young woman would have to have tremendous power... oh god."
** After Glory attacks Tara, Willow leaves the hospital enraged. When talking to Dawn and Spike later, Buffy assures them that she calmed down the powerful, heartbroken witch by talking to her. Spike and Dawn point out that if Buffy herself was in that position, she'd just pretend to be calmed down so her friend would leave.
* In the ''Series/TalesFromTheCrypt'' HowWeGotHere episode "Dig That Cat... He's Real Gone," homeless guy-turned-guinea pig Ulric, who's had a cat's special gland implanted in him which gives him nine lives, has been buried alive for his last ever stunt (he gets killed but always comes back, and he's got one more life - his ninth), which will earn him beaucoup bucks. [[spoiler: Unfortunately it's only then that it occurs to him that [[DidntThinkThisThrough the cat had to be]] ''[[DidntThinkThisThrough killed]]'' [[DidntThinkThisThrough to get the gland out.]] Meaning he only had ''eight'' lives...]]

* {{Eminem}}'s "Stan."
-->''I seen this one shit on the news a couple weeks ago that made me sick.''
-->''Some dude was drunk and drove his car over a bridge,''
-->''and had his girlfriend in the trunk, and she was pregnant with his kid,''
-->''and in the car they found a tape, but they didn't say who it was to.''
-->''Come to think about, his name was... [[FridgeHorror it was you]].''
-->''[[OhCrap Damn...]]''
* In Music/JonLajoie's "WTF Collective", MC Uses Time Machines Irresponsibly does this:
-->Then I traveled in time to the night I was conceived\\
I met up with my parents and we hung out all night\\
Come to think of it, they didn't have any alone time... [[PuffOfLogic NOOO]]-- \\

* [[TheFagin Fagin's]] song in {{Theatre/Oliver}}, "Reviewing the Situation", is this trope in musical form. Having realized that the life of a criminal, with all its "trials and tribulations", might not be the best thing for him, and he muses over possible alternatives: getting married, living in society, getting an honest job. Each time, though, he comes to the realization halfway through that the "solution" he's describing would not be an improvement, leading him to conclude:
--> '''Fagin''': I think I'd better think it out again.
* Deianira has shades of this in ''Theatre/TheTrachiniae'' as she talks to the chorus about the "strange sight" that is the bubbling, disintegrating piece of cloth she used to smear a love potion onto a shirt she just gave her husband.

[[folder:Video Games]]
* ''{{Starcraft}}'': "It's a zergling, Lester. A smaller type of zerg. But one of them wouldn't be out this far unless... OH SHIT!"
** [[DyingDeclarationOfLove "I love you, Sarge!"]]
* ''VideoGame/StarControlII'': The Slylandro purchase a probe from the Melnorme, which would explore the galaxy, replicate itself periodically, and report back once it finds something interesting. However, in the midst of an in-depth discussion of said probes with the player, they realize that, due to an attempt to get the probes to replicate faster (by changing the priority of replication to 999, the highest setting on the dial), they have inadvertently caused their probes to attempt to procure raw materials for replication from ANYTHING they encounter, with a special priority on alien ships. This has effectively transformed their peaceful exploration fleet into a HordeOfAlienLocusts.
* In ''VideoGame/FalloutNewVegas'', you can meet an OutlawCouple who think that an antique machine gun makes them dangerous enough to go on a crime spree through the Strip. If the Courier sarcastically says it's the most brilliant plan he/she has ever heard, the Bonny of the duo starts gloating about how they've got it all worked out, gradually noticing all the holes in the plan until she realizes they have no idea what they're doing and hands the gun over to you.
* In ''VideoGame/{{Psychonauts}}'', after a training session gone awry in Sasha's mind, Raz asks him what would happen if one were to block off all of a mind's censor outlets, which needless to say he'd just done.
-->'''Sasha''': Well, there would be a buildup of censor energy within that would, ah, eventually... Run, Razputin. Very fast.
* [[MadScientist Mordin Solus]]' introduction and EstablishingCharacterMoment in ''VideoGame/MassEffect2'' begins with Mordin performing a SherlockScan on the newly-arrived Commander Shepard and his/her team, while [[ThinkingOutLoud verbalizing his inner monologue]]; assuming the player doesn't interrupt him, he determines that the characters aren't from the area, too well-armed to be refugees, too informally-dressed to be any of the local mercenaries, and that they aren't there to wipe out the Vorcha or to investigate ThePlague's usefulness as a bioweapon. Eventually, he decides that they must be looking for someone important, someone with secrets... and then realizes that they're almost certainly looking for him.
** It happens ''again'' a minute later when Shepard explains that he/she was sent by a privately-funded human group to recruit Mordin. Immediately, Mordin starts sorting through a long list of possible candidates for the aforementioned group. After disregarding the [[TheFederation Alliance]], the [[SpacePolice Spectres]], [[ThoseWackyNazis the Terra Firma Party]], he finally realizes (with some shock) that the most likely candidate is Cerberus, a terrorist group with human-supremacist leanings.
** There's a darker example in ''VideoGame/MassEffect3'' that also involves Mordin (or Padok Wiks, if Mordin died in the second game). If Shepard chooses not to tell anyone that [[spoiler:the salarian STG sabotaged the genophage cure years ago and Shepard was informed of this in advance]], and then tries to dissuade Mordin/Padok from going up the Shroud tower, Mordin will wonder why, since Shepard doesn't seem concerned for his safety. So is Shepard convinced Mordin might discover something? Well then it must be [[spoiler:sabotage]], but whose?...[[OhCrap Ah.]] In Padok's case, he'll wonder why Shepard would abandon his/her goal after having come so far...unless there's something up there he/she doesn't want Padok to discover. [[spoiler:The temperature malfunction wasn't an accident; Shepard knew about this!]]
* Odd inversion from ''VideoGame/KingdomsOfAmalurReckoning'' where [[JadedWashout Agarth]] starts off angry then calms down as the facts hit (He just saw you ScrewDestiny and use it as a weapon).
--> '''Agarth:''' "[[WhatTheHellAreYou What are you!?]] DO YOU KNOW WHAT YOU'VE DONE!? Do you know how many lives will remain untouched by his death!? How many children won't be born!? (calming down) How many people... he won't kill..."
** It helps that [[ScrewDestiny the destiny you just screwed]] happened to be the one that [[spoiler:would have resulted in his messy death]] not two minutes prior to the conversation.
* ''VideoGame/KingdomOfLoathing'''s "Heavy Rains" special challenge path [[BaitAndSwitchBoss replaces most of its usual bosses with a watery imitator]]. Luckily, there's [[TemptingFate absolutely no way that would ever work]] on the [[SlippySlideyIceWorld Icy Peak]]!
--> I mean, it's freezing up here! A water-based giant winged yeti would have to be...made of...oh, crap.
--> A huge winged yeti that appears to be sculpted out of ice emerges from the mist, takes off into the air, and swoops toward you.
* Pretty much anytime [[Franchise/AceAttorney Phoenix Wright or other characters]] point out a contradiction that puts their client into deeper hot water is bound to turn into this. Bonus points if it requires the prosecutor to explain why this is a problem for them.
* At the end of ''VideoGame/QuantumConundrum'', Prof. Quadrangle finally recalls what he was doing before he got trapped in the pocket dimension. [[spoiler: Unfortunately, he remembers too late that turning on the Uber-IDS -- like [[NiceJobBreakingItHero he just told you to]] -- was what started this mess in the first place, and you end up causing a nearly-catastrophic dimensional instability as the overloaded Uber-IDS causes the whole world to shift through the light, heavy, slow-mo, and anti-gravity dimensions.]]

* In chess, one of the methods for dealing with a speculative sacrifice by an opponent is known as the ''show me'' method. If you can't see the point of the sacrifice, or even if you do see the point but don't think it will be all that effective, the recommended course of action is to accept it and continue playing natural moves, daring the opponent to show you their idea. Sometimes this works and the sacrifice fails. When it succeeds, however, you end up with this trope.

[[folder:Web Comics]]
* It happens in [[http://www.pholph.com/strip.php?id=5&sid=3285 this]] page of ''Webcomic/{{Jack|DavidHopkins}}'' (it's safe, for once.)
* It's more of an Explain Explain Oh My moment, but... ''Webcomic/{{Freefall}}'' [[http://freefall.purrsia.com/ff800/fv00710.htm has one somewhat like this.]]
* ''Webcomic/SchlockMercenary'''s Kevyn learns that there is a right time and a wrong time to invoke this on someone [[http://www.schlockmercenary.com/d/20070204.html here.]]
** During the Under New Management arc, Kevyn and Tagon discuss their current mission; being blackmailed by Xinchub into hunting down Kevyn's sister Breya. If they don't, Xinchub will have the Toughs arrested for a number of crimes. When Kevyn remains unhappy, Tagon asks who Xinchub will send after Breya once the Toughs are imprisoned. Kevyn responds, "I don't know... Some unimaginative, trigger-happy rear admiral, I guess." ''(Beat)'' "Oh, crap. I can't believe I ''just now'' figured that out."
* ''Webcomic/{{Xkcd}}'': "[[http://xkcd.com/852/ How did the pole vaulters get up to our balcony?]]"
* In ''Webcomic/DarthsAndDroids'' [[http://www.darthsanddroids.net/episodes/0573.html this]] happens to Annie when she finally tells Jim that she'd lost her job and in that same frame of time realizes it wasn't his fault entirely.
* ''Webcomic/ElGoonishShive'' had a [[http://www.egscomics.com/?date=2006-03-24 hilarious version]] with [[GenderBender female Tedd]] and too reasonable Susan.
** And another, slightly [[http://www.egscomics.com/index.php?id=1596 more dramatic one]] with Elliot: "I care deeply about her and I want her always to be a part of my life! I don't want to hurt her! [[spoiler: She's like a sister to me!" ... When talking about his then-girlfriend, Sarah.]]
** [[http://www.egscomics.com/index.php?id=1925 Later]], Grace is ''sure'' that if Justin has a magic mark, he ''must'' know about it.
---> How could he miss a small flame shaped mark colored slightly different from the rest of his skin on a spot high up on his back where he'd need a mirror and probably have to make a deliberate effort to '''''dammit'''''
* In GeneCatlow, Gene Catlow and [=CatsWhisker=] are discussing the First Animen, who are hostile to them. CW wonders how beings so ancient who have been in psychic contact with so many minds remained sane[[spoiler:--and Gene realizes that they didn't]].
* In [[http://www.giantitp.com/comics/oots0688.html "The Comics Must Flow"]], a strip from ''Webcomic/TheOrderOfTheStick'', Belkar is chugging [[Franchise/{{Dune}} spice in the middle of the desert]]. Seeing his eyes change color, Haley insists he read the warning label to avoid getting sick.
-->'''Belkar:''' No, it doesn't say anything about eye color change. Just a disclaimer that the distributor is not liable for any gruesome violent deaths resulting from consuming this product in an open desert. So, see? It's perfectly safe for-- ...Ah, crap.\\

* In [[http://www.smbc-comics.com/?id=3337#comic this]] ''Webcomic/SaturdayMorningBreakfastCereal'' comic, a woman claims she has invented a time machine and went back twenty minutes, where she saw a a huge flash of energy and then an empty void. She concludes that reality came into existence twenty minutes ago. Someone takes a look at the footage and tells her that she's wrong. [[spoiler [[EarthShatteringKaboom The machine was set to look forwards in time instead of backwards.]]]]

* This happens twice to WebVideo/ToddInTheShadows during his review of Music/OneDirection's "Best Song Ever", as his criticisms fall flat and he starts to realize that [[GuiltyPleasures he actually likes the song]].
* The Tabletop episode on TabletopGame/ChezGeek has this happen to [[spoiler: Storm]] when he plays the card Guy on the Couch. [[spoiler: Wil]] asks him to explain the card, which leads to this:
-->'''[[spoiler: Storm]]:''' Guy on the Couch gives you Slack +1. You can play him at any time without rolling, but starting on the next player's turn, he'll go away if... oh, I'm an idiot.
** To give this moment context, on the next player's turn, Guy on the Couch moves to the room of the player with the most Person cards in play. This meant that [[spoiler: Storm]] almost instantly lost the card.

* In the ''WesternAnimation/PinkyAndTheBrain'' episode "Brinky," Pinky's genetic material accidentally gets introduced into Brain's cloning experiment, essentially resulting in their having a child together.
-->'''Pinky:''' I'm a mommy, I'm a mommy!
-->'''Brain:''' Pinky, that's absurd! You are nothing of the kind. Its chromosomal makeup just happens to include both of our genetic building blo-- ''AAAH!!'' ...Oh my Lord, you ''are'' its mommy.
* ''WesternAnimation/{{Futurama}}'', "A Clone Of My Own", with Prof. Farnsworth's clone, Cubert:
-->'''Fry:''' Nothing is impossible! You'd know that if you really took after the professor, like I do.\\
'''Cubert:''' You're his uncle, dummy. ''He'' takes after ''you''.\\
'''Fry:''' Uh, wha?\\
'''Cubert:''' Wait a minute. That means ''I'' also take after you! AAAH!
* ''WesternAnimation/TheSimpsons'':
** One scene in an episode has Homer asking why he's such a loser. Bart replies, "Your father was a loser, and his father, and his father - it's genetic, man!" ({{beat}}) "[[BorrowedCatchphrase D'oh!]]"
** In the episode "Team Homer", the rain turns the students' gray school uniforms into bright rainbows.
-->'''Principal Skinner:''' I don't understand; I bought them the same place I buy Mother's dresses--''oh dear God, Mother's in the park!''
** Plus, in "I'm Going To Praiseland", Ned finds out that the citizens that were having "visions" were actually the effects of a gas leak in his Christian amusement park. Homer tells Ned to ignore it because his park spreads a positive message of equality. Then comes this...
-->'''Homer:''' Rich laughing with poor, bullies breaking bread with nerds, orphans lighting candles over a leaking gas line--'''''LIGHTING CANDLES?!?!?'''''
** Inverted in the Treehouse of Horror episode, "[[Literature/TheIslandOfDoctorMoreau The Island of Dr. Hibbert]]," when Homer is trying to argue against Dr. Hibbert's insane experiments:
-->'''Homer:''' All you can do is eat, and sleep, and mate! [[OneOfTheseIsNotLikeTheOthers And roll around in your own filth!]] And mate, and eat--where do I sign up?
* In the Halloween Episode of ''WesternAnimation/{{American Dad}}'' where Stan is trying to make his haunted house better than his neighbors by displaying live serial killers in glass cases.
-->'''Roger''': Stan, don't worry I've fixed everything...I let the prisoners out!
-->'''Stan''': You what?!
-->'''Roger''': Yeah, Francine was right. A shark's not intimidating behind glass, but when you're in the ocean with it-
-->'''Claus''': But Roger, they're going to kill us all!
-->'''Francine''': AND CHOP OFF MY HEAD!
-->'''Roger''': Scary, right?....[[OhCrap ahh, I never think things through.]]
** In another episode, Stan's on a fishing trip, and says he's glad to be out of the house, because it's the first anniversary of a huge fight he had with Francine. When asked what the fight was about, he says he forgot their anniversary. His co-worker is about to point this out to him, but Bullock stops him. Stan then screams when he realizes what he's done, and Bullock smiles and says, "There it is!"
* In the ''WesternAnimation/KimPossible'' episode "[[Recap/KimPossibleS4E17CleanSlate Clean Slate]]", Dr. Drakken starts describing how he drove all the soldiers off a military train by activating an overload alarm... and then reveals/realizes that he caused an ''actual'' engine overload rather than a false alarm.
* Brainy Smurf in ''WesternAnimation/TheSmurfs'' episode "The Sky Is Smurfing", who tries to remain calm while explaining the current situation of Mount St. Smurf erupting before he has the OhCrap moment.
* In an episode of ''WesternAnimation/XiaolinShowdown'', a [[FaceHeelTurn Face-Heel-Turned]] [[spoiler: Raimundo]] is chasing some of our heroes around in a forest. This is what our heroes wanted, however, as a diversionary tactic so an attack on Wuya's palace could succeed. Eventually, [[spoiler:Raimundo]] realizes that the chase is taking much longer than it should.
-->'''[[spoiler:Raimundo]]''': What's wrong with you guys, why don't you just fly away?! It's like you're not even ''trying'' to get away...[[OhCrap because you're NOT! Quick, back to the palace!]]"
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': In the episode "[[Recap/MyLittlePonyFriendshipIsMagicS3E11KeepCalmAndFlutterOn Keep Calm and Flutter On]]", Discord decides he's not going to go through with the ponies' attempts to turn him good. Why should he? He's free at last, and the only things that can really stop him, the six Elements of Harmony, aren't working due to Fluttershy (one of the six Elements) giving her word that she will not imprison Discord again as a show of trust. Discord breaks this trust, saying he doesn't care if Fluttershy stops being his friend. Why should he care? [[MyGodWhatHaveIDone She was only the first real friend he's ever had...]]
--> '''Discord''': Well played, Fluttershy, well played...
* In ''WesternAnimation/DonkeyKongCountry'', as part of a ZanyScheme, DK flies around in Funky's bi-plane.
-->'''DK:''' Hey, it's Dixie's pet crab! Aw, isn't cute, eatin' through all those funny-lookin' wire- This is definitely a bad thing. ''Ahh! The plane is out of control!!''
* In ''WesternAnimation/MoralOrel'', in one episode Orel popularizes a song from the point of Judas called "I Hate You Jesus". It becomes a hit in town, and soon everybody starts singing it in church. Orel is at first pleased with its success, but then this trope comes into play as he says, "Wow, everybody sure hates Jesus! ''Whoops''."
* ''WesternAnimation/{{Rugrats}}'':
** From "Grandpa Moves Out":
-->'''Didi:''' "Say, didn't those kids speeding by on the electric scooter look just like Tommy and Angelica?"\\
'''Drew:''' "Yeah, they sure did."\\
'''Didi, Stu, Drew, and Lou:''' "Tommy and Angelica?!"
** From "Turtle Recall":
-->'''Chas:''' "Of all the places to leave an empty stroller! Some people just..." (beat) "Empty? Stroller? Stu! Where are the kids?"
** A delayed-reaction example takes place in "Passover". It takes place during an [[ImagineSpot Imagine Spot]] where the babies are all characters from the famous Moses and the Ten Plagues story. Angelica plays the hard-hearted Pharaoh in this retelling, and interestingly she's still her child self, rather than an adult. Of course she refuses to let Moses' people go even after most of the plagues, so eventually God gets to the last one, killing off the "firstborn" of every Egyptian. Angelica laughs it off at first...and then she asks her father who the firstborn of ''her'' family is. Her father explains that since Angelica is an only child, the firstborn would be ''her!'' Her father doesn't know about the coming plague, but the implications certainly sink in for ''Angelica'', whose reaction is this trope.
* In the ''WesternAnimation/SupermanTheAnimatedSeries'' episode "[[Recap/SupermanTheAnimatedSeriesS2E13MonkeyFun Monkey Fun]]", Dr. Hamilton theorizes that the bacteria that just attacked him and his team grew because of exposure to a strange gas and then Earth's atmosphere. Then he remembers that [[EverythingsBetterWithMonkeys Titano]] had the same exposure, and he and Superman both have a moment of this.
* In the ''WesternAnimation/SpongeBobSquarepants'' episode "Just One Bite", Squidward has one when he breaks into the Krusty Krab to steal a Krabby Patty and triggers the burglar alarm.
-->'''Squidward:''' This is our burglar alarm? A bucket of water? (''Opens the door causing the bucket to spill'') That was too easy. (''Sniffs'') Hey, this isn't water, this is... gas! (''Match drops'')
** This scene was actually removed from the episode, as it occurred TooSoon after 9/11.
* ''Franchise/SonicTheHedgehog'' cartoons:
** In the ''WesternAnimation/AdventuresOfSonicTheHedgehog'' episode, "Sonic Breakout", Robotnik [[PrisonEpisode builds a giant prison complex and imprisons a cartoonist who made fun of him, and later on, Sonic]]. When Sonic gets out of his TailorMadePrison, Robotnik is with the cartoonist when alarm sounds.
-->'''Robotnik:''' (''to cartoonist'') "Hm? You haven't escaped. I would have noticed that. ''The Hedgehog!''"
** In one episode of ''WesternAnimation/SonicUnderground'', Robotnik creates a potion that gives its taker super-speed, which allows his minions, [[ThoseTwoBadGuys Sleet and Dingo]] to catch Sonic. Later, Robotnik sees Sleet's feet expand to the point where he can't move.
-->'''Robotnik:''' "Must be a side-effect. What a waste of a good invention. I wonder if the same thing's happened to- ''Dingo's guarding Sonic!''"
** In a different episode of the same series, Sonia and Bartleby are talking about something strange that a robot was doing, making them want to talk more about Dr. Robotnik.
-->'''Sonia:''' "What did I say? Chili, shampoo, massage, hm... ''(gasp)'' Oh no! "Cramped, dirty secret rebel base!" I can't believe I said that!"
* ''WesternAnimation/TheRealGhostbusters'' episode "A Ghost Grows In Brooklyn" includes this conversation as the four guys are climbing a wall, following the roots of a giant, monstrous, destructive plant back to its source:
-->'''Egon:''' Do you think there might be some significance in the fact that the giant plant is a geranium, just like the one I gave Janine?
-->'''Ray:''' Pure coincidence, Egon -- there must be a million geraniums in this city.
-->'''Egon:''' Right... besides, if it was the same plant, then the center of the whole thing would be...
