AliceAndBob are having a conversation. During the conversation, Bob says or does something that you'd think would [[BerserkButton set Alice off]]; however, she goes right on with the conversation as if it never happened. Until 30 seconds or so later...

Alice just had a Delayed Reaction. Basically, her brain somehow took longer to make a connection that the audience makes right away. Doesn't always have to be something designed to anger people, though those work best. Bonus points if the character walks off-screen, then yells something said out loud and races back.

Compare ITakeOffenseToThatLastOne, LateToThePunchline and ComebackTomorrow. See YouAreAlreadyDead for the combat version. Often follows a {{Beat}}.

[[folder:Anime & Manga]]
* ''Manga/OnePiece'' did this with Ivankov, second-in-command to protagonist Luffy's father (who, for context, is the world's most wanted criminal, and only a handful of people in the world are even aware that Luffy is related to him). Luffy remarks "Oh... you mean my dad?" and the person he's speaking to goes through an entire speech before jumping back in shock, yelling "YOUR FATHER?!"
** Non-YouAreAlreadyDead combat version: Luffy's fight with Blueno, which became a CurbStompBattle the second that Luffy starting using his new Gear Second ability, culminates with Luffy using his Gum-Gum Jet Bazooka, and Blueno attempting to guard against it with his strongest [[SuperToughness Tekkai]]. Luffy hits him in the stomach, ''hard'', but he just slides several feet backwards from the blow's impact, and then looks up to grin at Luffy. But just as Luffy is about to pull out his other new trump card, Blueno passes out; not even his strongest defense was enough to protect him.
*** Luffy has this mindset in general (when not in a fight or angry that is). The best example being during the drum island arc he and Sanji are running through a castle filled with ice and snow, wearing thin clothing and it takes him a few seconds to realize that he's cold, though that could have something to do with the way rubber conducts heat.
* In ''[[VideoGame/HarukanaruTokiNoNakaDe Harukanaru Toki no Naka de - Hachiyou Shou]]'' {{OAV}} episode "Omoi no Arika", [[TrappedInAnotherWorld Akane, Tenma and Shimon]] discover a letter -- the audience is aware that it's from [[SmallAnnoyingCreature Kotengu]], who wants to challenge [[{{Onmyodo}} Yasuaki]] to a duel. Apparently, Kotengu's handwriting is too fancy for them to understand, so they have one of the locals, Tomomasa, read said letter to them aloud. After he finishes, Akane and Shimon are amazed by the fact Tomomasa could read that, saying they are ''so glad'' they know now what the letter says, as they could never imagine that it's a challenge... Cue a short pause, with a still shot of the two smiling happily and a dot-by-dot VisibleSilence above them... after which both yell in horror: "''A challenge?!''"
** The first episode of ''Harukanaru Toki no Naka de - Shiroki Ryuu no Miko'' OAV ends with Karin being told that she is the titular {{miko}}; Karin's first reaction is a happy smile... then, a few seconds later, the smile disappears as it finally dawns on her what these words mean: "Eeeh?! Me?!"
* In one episode of ''Anime/NerimaDaikonBrothers'', the characters are eating ramen together. Hideki asks Ichirou if he shouldn't be getting to work, and Ichirou replies that he's going to Kabuki-chou (Tokyo's infamous red-light district) tonight instead. The others continue to eat for a few seconds before [[SpitTake spit-taking]] the ramen.
* In ''Manga/TheWeathermanIsMyLover'' the main characters have a {{manzai}} dynamic on-screen which mostly entails Amasawa making inappropriate or awkward remarks and Koganei not reacting to them at all. Amasawa manages to catch him offguard twice, leading to noticeably long delays before Koganei resumes reporting-as-usual. The viewers go wild over this.
* In ''Manga/SoulEater'', Asura awakens after centuries of [[SealedEvilInACan sleeping in a bag made from his own skin]] and barely displays any awareness of his surroundings. While blindly walking around, he bumps into Eruka, who's slumped on the ground and too terrified of him to even move. He then bends down and opens his eyes for the first time to look at her while she's still paralyzed in fear. After ten seconds of staring, he starts a ReactiveContinuousScream. Why? ''Because he was startled by her''.
* In an episode of ''Ultimate Girls'', the main girls are in various states of dress and undress when the word "monster" gets thrown out. Cue Makoto, resident {{Kaiju}} obsessed journalist and CameraFiend, barging into the room, taking several photos, ''reloading his camera'', and taking ''more'' photos before realizing his mistake and walking out of the room in ''disappointment.'' Seconds go by before the first girl screams in embarrassment.
* [[NiceGuy Mikado]] from ''LightNovel/{{Durarara}}'' had a very funny delayed reaction in episode 3 when [[{{Jerkass}} Izaya]] was hit by a vending machine. To be fair, the vending machine was going very fast.
* Yuuichi and Makoto from ''VisualNovel/{{Kanon}}'' share a delayed reaction after Yuuichi, naked, walks in on her bath accidentally; it's so sudden the [[MusicalisInterruptus music cuts]] instantly for maximum effect. It lasts for almost ''[[OverlyLongGag half a minute.]]''
--> '''Makoto''': *Blank Stare*
--> '''Yuuichi''': *Blank Stare*
--> '''Makoto''': *Blank Stare*
--> '''Yuuichi''': "Y... Yo!"
--> '''Makoto''': *Blank Stare*
--> '''Yuuichi''': "My bad, I wasn't paying attention and didn't notice you were here. ...uh, anyway, it must be fate that brought us here together! I'll just join yo-
--> '''Makoto''': ''"GAAAAAAAAAAAH"''
* In ''Manga/KOn'' each of these bits of bad news take a few seconds to sink in:
** Nodoka mentioning the upcoming midterms to Yui.
** Yui saying she's banned from club activities since she has to take a make-up exam.
** Tsumugi telling Yui their club is not officially recognized, and their request to use the use the gym is denied.
* ''[[Anime/TengenToppaGurrenLagann Lagann-hen]]'' has a hilarious moment when the [[HumongousMecha Chouginga Gurren Lagann]] warps into Anti-Spiral territory and the BigBad sends a huge wave of what looks like water at them.
-->'''[[BridgeBunny Cybela]]:''' Is that... a ''tsunami?!''
-->'''Dayakka:''' [[LampshadeHanging Why is there one in space...?]] ''(wave tumbles the planetoid-sized mecha over like a toy)'' '''WHAT THE HELL IS A TSUNAMI DOING IN SPACE?!'''
* In ''Manga/SangatsuNoLion'', Takahashi brings a tape of Rei's losing MHK Cup match to the Kawamoto residence, not knowing that Rei has kept the fact that he's a professional shogi player a secret from Hina and Momo. When they see Rei on the television screen, it takes them several moments until they realize what the implications are of Rei being on broadcasted television.
* In the beginning of ''Manga/GekkanShoujoNozakiKun'', it took Sakura ''four hours'' to realize Nozaki was a {{mangaka}}. She even helped him with his manga the whole time!
* Joey from ''Anime/YuGiOh'' has a memorable moment in Season 5.
--> '''Kaiba''': Anyone late for registration will be disqualified. Mokuba, makes sure Wheeler is late.

[[/folder]]

[[folder:Comic Books]]
* From ''{{Broom-Hilda}}'', the titular witch is in a rage, complete with moons, stars, swirls, pound signs, and everything else used to cover up [[{{Bowdlerise}} what she's really saying]]. Another character chides her, saying that "swearing is a childish way to assert one's masculinity". It doesn't occur to her until the next panel what the word "masculinity" means.
* Used as a RunningGag in ''GrooTheWanderer''
--> '''Someone''': Groo, you can not understand this, since you are slow of mind.
--> '''Groo''' (pages later): ...What he mean "slow of mind"?
[[/folder]]

[[folder:Film]]
* This happens in one scene in the movie ''Film/HouseParty'' (Note that there are scripts of this movie online, but the dialogue in the actual movie seems to be adlibbed somewhat. This is from the movie, not the script):
-->'''Thug 2''' (saying this while being handed a baseball bat) Alright cool...Finally, a program I'm with. Whatever this is, I'm with it. (While thug 1 picks up a can of gasoline) Oh I hear that, I hear that. We gonna bust their ass as they come runnin out of the burning house.\\
'''Thug 2 and 3''' (in unison): Burnin house?\\
'''Thug 1''': Burnin house...\\
'''Thug 3''': Damn Stab, Stab (Thug 1) hold up for a second. l was talking about kicking some fucking ass...not burning people up.\\
'''Thug 2''': Yeah now you're going too far.
* From the ''Series/SesameStreet'' [[TheMovie movie]] ''Big Bird in China'', Big Bird needs to find a camel. That's all he knows. Naturally, there are no camels in China, so he goes sightseeing in a sculpture garden...
-->'''Big Bird''': "Oh, look, there's an elephant. And there's a camel. And there's an orangutan. My these sculptures are pretty..." ''He walks off-screen, then...'' "A CAMEL?!?"
* In the Russian film ''Film/{{Morozko}}'', there's a group of girls picking giant mushrooms in a forest. They see a bear, but it takes them almost 20 seconds to run away. [[MST3K Mike Nelson]] refers to it as "Delayed reaction syndrome".
* In the 80s Vietnam flick ''Film/HamburgerHill'', a radio operator survives a nearby explosion. When the smoke clears, he is still doggedly trying to use his set, until he turns his head to discover that he's lost an arm. Disturbingly, he mutters "Oh." upon seeing his injury.
* Charlie in ''Film/MysteryTeam''. He is the last person to connect the dots, attacks Jason ten seconds after realizing it was him, and understands a pun the group made eleven years prior.
* From ''Film/DumbAndDumber'', in a scene where Lloyd finds a newspaper clipping of the Moon Landing (over 25 years before the film was made):
--> I can't believe it! We landed on the moon!
* Creator/LaurelAndHardy: Stan and Ollie are usually also very slow to realize what's going on around them.
[[/folder]]

[[folder:Literature]]
* Referenced in a ''Literature/{{Discworld}}'' story when Nanny Ogg tells Casanunda that she "nearly fell off her broom from laughing" when she saw a burial mound from the air. Said burial mound is two circular mounds connected to one end of a long barrow mound, so...
** Another example is in ''Discworld/{{Jingo}}'' where [[LeonardoDaVinci Leonard of Quirm]] very briefly mentions in the middle of a long rambling conversation full of useless information that [[spoiler: many years ago he did some sketches of an island that has supposedly only appeared recently]]. The person he's talking to doesn't realise the implications of this until he's left the room, at which point he quickly comes back to ask for clarification. Two things are notable about this example: 1. The person he's talking to is [[MagnificentBastard Lord Vetinari]], who is normally ''very'' quick to notice important details, making it particularly funny that he should be a victim of this trope, and 2. Unlike many uses of this trope, the relevant information actually ''is'' quite easy to miss if you're not paying attention, and the reader may end up doing exactly what Vetinari did.
* In ''Literature/TheHitchhikersGuideToTheGalaxy1'', Arthur sees several big yellow bulldozers outside his window, but he's so hung over that only pieces of the concept register at first, one at a time. It takes several minutes for him to remember[[note]]As he'd been notified just last night; he was hung over because he'd been [[DrowningMySorrows driven to drink over it]][[/note]] they've come to knock his house down.
-->The word ''bulldozer'' wandered through his mind for a moment in search of something to connect with.\\
''[later in the scene]''\\
The word ''yellow'' wandered through his mind in search of something to connect with.\\
[[OhCrap Fifteen seconds later he was out of his house]] and lying in front of a big yellow bulldozer that was advancing up his garden path.
[[/folder]]

[[folder:Live-Action TV]]
* From the ''Series/StarTrekTheNextGeneration'' episode [[Recap/StarTrekTheNextGenerationS5E20CostOfLiving "Cost Of Living"]], featuring Troi, her mother, Worf, and his son. After hearing that Worf and the boy are "having trouble [drafting a] contract", Mrs. Troi goes doting on the boy:
-->'''Mrs. Troi''': Why of course he's unreasonable, he's a child! And such a child! You know, making children reasonable only gives them pimples!\\
'''Troi''': Alexander, this is my mother.\\
'''Mrs. Troi''': Alexander? What a wonderful name! I used to know a warrior named Alexander, he utterly adored me. And we went everywhere, simply everywhere together! Have you ever been anywhere, my little -- CONTRACT, WHAT CONTRACT??
** Also from TNG, ''Film/StarTrekGenerations'' has Data first use his emotion chip, which sets off the galaxy's biggest delayed reaction ever as he finally understands a joke Geordi made seven years earlier.
* Appears in a ''Series/MontyPythonsFlyingCircus'' sketch involving a series of police inspectors with strange names. When one introduces himself as "Lookout, of the Yard," one of the other characters asks "What will we see?" The inspector starts laughing about 30 seconds later, as he [[LateToThePunchline finally gets the joke]], when he's in the middle of talking about the murder case.
* In the ''Series/{{MASH}}'' episode, "38 Across", Radar was walking across the compound and passed Klinger, who said he was eating a jeep. Radar went on about his business and until he got back to his office, then suddenly processed what Klinger had said and told Col. Potter.
* The short-lived sitcom ''Series/OliverBeene'' had an interesting take on this one. In the middle of a game of charades featuring Oliver's parents, the Dad explodes in fury at his wife, and calls her stupid. She calmly smiles, and offers her guests dessert. The narrator (Oliver) states that for his mother, her anger was like a giant casserole. It's made, and then baked in the oven for an uncertain amount of time. Two scenes later... "Remember that giant casserole of anger? It's done...right...about...now." ''(DING)''
* ''Series/FatherTed'' has several examples.
** From "Speed 3", Dougal has taken over as milkman after Ted gets KavorkaMan Pat Mustard sacked. The housewives on Mustard's route, still expecting Mustard, answer the door nude when Dougal comes knocking, but Dougal seems completely oblivious to this as he delivers the milk. At the very end of the episode, he suddenly sits bolt upright in bed and shouts, "THOSE WOMEN WERE IN THE NIP!!!"
** In "Kicking Bishop Brennan Up the Arse", Ted does just what the title says after losing a bet with Father Dick Byrne. Bishop Brennan is so shocked he cannot process what has just happened until some time later, when he is in Rome for an audience with the Pope. Just as he is being introduced to His Holiness, Bishop Brennan roars, "HE ''DID'' KICK ME UP THE ARSE!!"
** Also a bit where Ted thumps Dougal on the head with a pencil, and it takes several seconds for the pain-report to arrive in Dougal's brain.
* In ''Series/TheWestWing'' when Leo offers a job to Ainsley Hayes:
-->'''Ainsley:''' I'll ask again: for what purpose was I brought here today?
-->'''Leo:''' So I could offer you a job.
-->'''Ainsley:''' I'm asking because I do not think that it is fair to be expected to play the role for the mouse to the White House's cat in the game of...you know the game.
-->'''Leo:''' Cat and Mouse?
-->'''Ainsley:''' Yes. And it's not like I'm not, you know. The fact that I may not look like some of the other Republicans who cross your path does not mean that I'm any less inclined toward...
-->'''Leo:''' Here it comes.
-->'''Ainsley:''' Did you say offer me a job?
* ''ICarly'': Used a bunch of times throughout the series, usually by Freddie and Spencer.
** In ''[=iMust=] Have Locker 239'', Freddie negotiates with Sam about getting her half of the locker as Sam mentions that her mom is driving a car to fetch her just ''after having an eye surgery''. Freddie still goes on his negotiation until Sam's statement sinks in.
** In ''[=iHurt=] Lewbert'':
--->'''Carly''': Lewbert got hurt, which brought out your mom's motherly instincts.
--->'''Sam''': So, what if you... ''got hurt''?
--->'''Freddie''': Yeah... (pauses) '''WHAT?!'''
* ''Series/{{Friends}}''. In [[TheOneWith The One Where]] [[spoiler: Rachel]] [[TheOneWith Is Pregnant]], the other two girls and Joey are trying to figure out [[WhosYourDaddy who the father is]]. Their only clue: a man's sweater left behind in mommy's apartment a month ago. While the three of them are discussing this, [[spoiler: Ross]] walks in, talks with them for a bit, and then says, "Oh, hey, my sweater! I've been looking for this for like, a month!" Cue EyeTake from the girls, while Joey just sits there. [[spoiler: Ross]] leaves, and ''then'' Joey freaks out.
** This is almost a RunningGag with Joey, who has several of these throughout the series.
-->''(Joey, in deep thought, can't yet put together that the sex tape in Richard's apartment labeled 'Monica' is probably referring to their friend)''
-->'''Chandler''': GET THERE FASTER!
** Probably the most memorable is in the finale when Monica and Chandler [[spoiler: bring home their adopted children, which everyone believed was only one child, not two.]] Everyone reacts in shock except for Joey, who asks what the big surprise is, putting 2 and 2 together shortly afterward.
* On ''Series/TopGear'', while reviewing a Lamborghini Reventon (the Spanish 'v' is pronounced like a 'b'), Jeremy Clarkson makes a [[GettingCrapPastTheRadar sly comment]] that owning one would get you "a lot of badge." At least a full second goes by before his co-presenter Richard Hammond gets the joke.
* ''Series/TheITCrowd'': Roy rants that Jen knows nothing about computers and will someday slip up in something she says or does. Moss cuts in to say that the computer Jen is pretending to use isn't plugged in. Roy continues to rant and storms out. Moss says "He'll realise in a moment." He does.
** The failed US pilot delays the reaction further; Roy re-enters the office, claims a pen from the desk, and leaves before the realization.
* In the ''Series/MysteryScienceTheater3000'' episode ''Prince of Space'':
-->'''Tom:''' Talking like what?
-->'''Mike:''' Why're you talking like that?
-->'''Tom:''' Well, no, I'm not, I'm just way ahead of you, Mike.
-->'''Mike:''' Well, like that, you know? You're answering my questions before I ask them. [...]
-->'''Tom:''' No, you dope, I mean I'm moving faster than you ''temporally'' speaking.
-->'''Mike''' ''(insulted)'': Hey, whaddya mean you're way ahead of me?
* ''Series/DoctorWho'':
** In the episode [[Recap/DoctorWhoS29E6TheLazarusExperiment "The Lazarus Experiment"]], at the beginning of the episode, as the Doctor is planning to leave, he hears a scientist on television talking about how he's going to "change what it means to be human." He takes little notice of it as he sets off, and the TARDIS fades... and then slowly reappears. The Doctor pops his head back out and says "I'm sorry... did he say 'change what it means to be human?'"
** The Doctor gets another one in [[Recap/DoctorWhoS31E12ThePandoricaOpens "The Pandorica Opens"]] with regards to [[spoiler:the reappearance of Rory Williams]].
--->'''The Doctor:''' Ooooh, I'm missing something obvious, [[spoiler:Rory]], something big, something slap in front of me, I can feel it.\\
[[spoiler:'''Rory''']]: [[DeadpanSnarker Yeah, I think you probably are]].\\
'''The Doctor:''' I'll get it in a minute.\\\
(''{{beat}}'')\\
'''The Doctor:''' (''pokes'') Hello again.
* ''Series/WhoseLineIsItAnyway'' has [[ExactlyWhatItSaysOnTheTin Delayed Reaction]] [[http://www.youtube.com/watch?v=WNvGJO2AaDc Man]].
* In an episode of ''Series/{{Coupling}}'' Jane tells Oliver not to worry about his brain, saying "Many plants don't have brains, have you thought about that?" It takes him almost a minute to realize the absurdity of that implication and correct her.
* ''{{Sanctuary}}'': Nikola Tesla drops one of these on Helen Magnus when he looks her up after about, oh, fifty years.
-->'''Tesla''': I brought you here for two reasons - because only you can help me finish what I'm working on and [[LoveConfession because I love you]].
-->'''Helen''': Yes, so you keep... what?
* ''Series/KenanAndKel'' has an example in the episode "Get The Kel Outta Here", revolving around a joke about a sculpture of Kel's head that Kyra has made for school.
-->'''Kenan''': What are y'all studyin', nasty freak monsters?
-->''(Kel laughs)''
-->'''Kyra''': This model happens to look exactly like Kel.
-->'''Kenan''': Like I said, what y'all studyin', nasty freak monsters?
-->''(Kenan, Kel, and Sheryl share a laugh)''
-->'''Kel''': Ha ha ha! YEAH! Ha ha... ha... hey... that's about me... with the freak monster...
* A real-life example: on the first episode of Season 2 of ''Series/TheVoice'', one of the people auditioning was Tony Lucca, who was a [[http://en.wikipedia.org/wiki/The_Mickey_Mouse_Club#1990s_revival.2C_The_All-New_Mickey_Mouse_Club_.28MMC.29 Mouseketeer]] with coach Christina Aguilera ... and she didn't realize that until he'd already finished his audition and left the stage.
* Done more than once on ''Series/FTroop'', with O'Rourke's comment to Agarn "I don't know why people say you're so dumb", followed up several minutes/scenes later with Agarn's "Who says I'm dumb?!"
* In an episode of ''Series/GoodLuckCharlie'' PJ procrastinates on going to the dentist, so Amy has him take a bite out of an apple to see if his teeth are in such good shape like he believes they are. A few seconds after PJ leaves the room, Amy begins counting, leading up to PJ's pained yell.
[[/folder]]

[[folder:Newspaper Comics]]
* In two consecutive strips of ''ComicStrip/CalvinAndHobbes'', Calvin remarks that he's "Not playing with a full deck [of cards]" and that he's "Lost his marbles [and hopes someone finds them]," to which Hobbes replies, "Everyone suspected as much." It is at night, in bed, when Calvin sits up and yells "HEY!"
** Happens a lot when Calvin claims to be a genius. In one strip, he loudly declares his ridiculously high intelligence, and Hobbes immediately asks him how he walked to the bus stop with both legs in one pant leg. Calvin replies that he fell down a lot, then a panel later, asks what Hobbes is implying.
* In ''ComicStrip/BloomCounty'' after a [[ItMakesSenseInContext "Nudity Week,"]] Bill the Cat, who has Donald Trump's brain, has this epiphany, which is then turned into a joke by Opus.
--> '''Bill:''' [...]That deep down, we're all the same person.
--> '''Opus:''' A rube with too much loot?
--> '''Bill:''' Yes... NO!
* In one ''ComicStrip/{{Garfield}}'' strip, Jon has just woken up when Garfield pops out of his dresser to scare him. Jon walks away, gets coffee, and comes back before he screams in fright.
* ''ComicStrip/USAcres'': [[http://garfield.com/us-acres/1993-07-22 Sheldon asked for a lick of Booker's ice cream. It took a few seconds for Booker to realize Sheldon couldn't lick through his shell.]]
** Also, when [[http://garfield.com/us-acres/1993-07-12 a worm impersonated a chopstick to trick Booker]], the worm talked to Booker, who called him "Mr. Chopstick" and only later realized how odd it was for a chopstick to talk.
[[/folder]]

[[folder:Video Games]]
* The Franchise/{{Pokemon}} Slowpoke. As described in the Pokedex, "It takes 5 seconds for it to feel pain when under attack." This actually has an in-game benefit as it generally translates into a larger than is typical amount of HP.
** [[MemeticMutation On the Internet]], it translated to a meme in which a person masquerading as Slowpoke responds in a delayed way, such as "Am I too late for 5 Million?" on the 6,000,00''1''st post of a forum, or [[Webcomic/SuperEffective reporting on the death of]] Music/ElvisPresley days after the death of Music/MichaelJackson.
** The funniest of these was someone posting on an {{image board}} about a [[TheUntwist plot reveal]] in ''Anime/CodeGeass''. The first response was someone stating that "I don't have a Slowpoke slow enough to respond to this, so I'll wait 2 years and do it then." [[CrowningMomentOfFunny Cut to 2 years later...]]
* At the beginning of the first ''VideoGame/MegaManBattleNetwork'' game Yai has one when Dex calls her a shrimp. (The dialogue is as follows)
-->'''Dex:''' Aww stuff it! You sure got a big mouth for such a shrimp! We're not bothering anyone are we Lan?
-->'''Yai:''' Well, I guess... Shrimp! That's no way to talk to a lady!
* In ''VideoGame/TransformersWarForCybertron'' Starscream declares that the Autobots are dumber than Skywarp. It takes a good 15 seconds for Skywarp to respond.
[[/folder]]

[[folder:Visual Novels]]
* In ''VisualNovel/ShikkokuNoSharnoth'' Angie is introduced to celebrity aristocrat Viola Baskerville and is so nonchalant about it that Mary is surprised. A few minutes later, she realizes who she's been making friends with and momentarily stops in shock... but then quickly continues making friends, reasoning there's no reason to start treating her differently now.
* Whenever a girl is over at Shirou's house in ''VisualNovel/FateStayNight'' or just near him, Taiga will end up greeting them and chatting for a bit. After a minute or two she generally blows up.
* In ''VisualNovel/GrisaiaNoRakuen'''s Prologue To Grisaia short story, Michiru accidentally goes to a middle school called Mihama rather than the actual Mihama high school and doesn't notice her mistake for ''two months'', at which point she's finally clued in by the fact that her uniform was different from everyone else's.

[[folder:Webcomics]]
* Seen in [[http://www.arthurkingoftimeandspace.com/0746.htm this]] ''ArthurKingOfTimeAndSpace'' strip. No, sorry, [[http://www.arthurkingoftimeandspace.com/0747.htm this]] one.
* A few instances of this occur in ExterminatusNow - like triggering the decoy SelfDestructMechanism.
--> '''Virus''': Damnit!\\
'''Lothar''': Ha, I win! ...Wait, shit.
* Doyt in ''Webcomic/SchlockMercenary'' does this to a [[http://www.schlockmercenary.com/2001-07-26 dig at his intelligence]].
-->'''Doyt''': Severe [brain damage] as in stupid? Or severe as in dead?
-->'''Haban''': Doyt, considering the fact it would be hard for a copy of you to get any stupider, I'd have to say 'dead.'.
-->'''Doyt''' (later that night): Hey...
* In ''Webcomic/ElGoonishShive'', Mrs. Kitsune [[http://www.egscomics.com/index.php?id=1307 gets through half a sentence]] before realizing Nanase just mentioned Tedd having a girlfriend.
[[/folder]]

[[folder:Web Original]]
* A running gag on ''WebVideo/AtopTheFourthWall'': Linkara will read a character saying a stupid plan or inaccurate statement, summarize it in a triumphant tone of voice, and then go "Wait..." with confusion in his voice.
* ''WebVideo/DragonBallAbridged'' gives us the following gem from their abridgment of the Lord Slug movie.
-->'''Piccolo:''' ...and that would make ''you'' no doubt [[TheBrute the big, tough, stupid one]].\\
'''Dorodabo:''' You take that back or I'll kill you!\\
'''Piccolo:''' All right, all right, you're not tough.\\
'''Dordabo:''' That's better.
-->*{{beat}}*\\
'''Gohan:''' Wait, didn't you-\\
'''Piccolo''': Give him a minute.\\
{{Beat}} {{Beat}} {{Beat}}\\
'''Dordabo''': ...Hey!
** The first speaking role of a [[CaptainObvious Kan]][[NoIndoorVoice ass]][[ItWasHisSled ian]] after his species is wiped out in the ''Bardock Special'' is rife with this. A ScareChord plays as one emerges from the rubble of his planet... {{Beat}} "I CAN SEE THE FYUUU-CHURRR!" He proclaims (upon realizing that they can see him) that he must stop Bardock's team from destroying his race "IN THE FYUUU-CHURRR!" and after they point out that they already did, it takes him a moment to formulate a response. He attacks and in return he is fried with a fiery ki blast, leaving him standing there burning to death for an extended shot... before finally realizing "I'M ON FIRE!" and being finished off.
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fan-named background pony "Princess Erroria" (so called because an animation error depicted her with both horn and wings) is often depicted riding around on a [[Franchise/{{Pokemon}} Slowpoke]] after people pointed out this animation error... over a year after the episode aired.
* From ToddInTheShadows' review of Music/BritneySpears' "Three":
-->'''Todd:''' "I literally cannot make out what she's saying. 1, 2, 3, Pita Parma, Peter Potamus... I don't know, I don't know."
-->''[video plays with subtitle: "1, 2, 3, Peter, Paul and Mary"]''
-->'''Todd:''' "Well, there's your problem right there! It's a terrible rhyme. It's pronounced 'Mary.' Not 'Myea-ree,' whatever your said. That just sounds stupid. It makes her sound like English isn't even her first lan... guage... '''''Peter, Paul, and Mary?!'''''"

[[folder:Western Animation]]
* ''WesternAnimation/AmericanDad'' demonstrates this trope in the episode where Stan [[ForgottenAnniversary forgets his anniversary]], again as seen [[http://www.youtube.com/watch?v=8ZNZN9PPEpA here.]]
* One ''U.S. Acres'' segment from ''WesternAnimation/GarfieldAndFriends'' dedicated to [[NoFourthWall discussing animation tropes]] had the ultimate example of this. Laidback sheep Bo walks past a friend of his, who declares that the farm is being invaded by aliens resembling dishwashing liquid. He does not react, instead heading into his pen and sleeping away the entire winter. Three months later, he steps outside, stretches... and then shouts "''Dishwashing liquid?!'' Head for the hills!" and runs away.
** Garfield himself does this in "The Amazing Odie," when he contemplates: "Everyday it's the same routine, I get up, I walk under the camel, I go to the kitchen, walk back under the camel and, wait a minute let's see, I get up I walk under the camel, go into the kitchen walk back under the camel, UNDER THE CAMEL!?"
* Happens often with Tom in ''WesternAnimation/TomAndJerry'', which makes him realize too late that he's carrying a bomb, about to get hit, or that Jerry is right in front of him.
** Jerry also has this happen to him in the 1945 short "The Mouse Comes to Dinner". As Jerry greedily munches on cheese and crackers, Tom hits him on the head with a spoon. Jerry keeps eating for a few seconds longer, then reacts to the blow on the head and keels over.
* WesternAnimation/WileECoyoteAndTheRoadRunner: Wile E. Coyote usually realizes very late that he's walking on thin air. Once he does he falls down.
* Played with in ''WesternAnimation/TheSimpsons'' where it appears that time is passing normally for the audience, whilst it is revealed that Homer's brain is actually working at the speed of dumb. "Something said, not good."
** Also, Homer's workmates call him "a little slow" on poker night in one episode. By the time Homer responds "How dare you call me that?!", it's hours later, and Lenny's asking Homer to go home already.
*** It should be noted that these two occasions are one-in-the-same: Homer's initial reaction to being called slow by Carl was to mull it over and have the delayed reaction. Lenny is in his nightshirt and cap when Homer finally asks about it, prompting him to say "Boy, you ''are'' slow!" Which then causes Homer to go through the exact same thought process again until Lenny tells him to leave.
** In "A Star is Burns", [[TheAhnold Wolfcastle]] has this happen to him ''twice''. When he realizes Jay Sherman (from ''WesternAnimation/TheCritic'') insulted him, he chases him down with an assault rifle. Sherman says his shoes are untied, and Wolfcastle replies "From here, they appear to be tied, but I will go in for a closer look". Sherman beats a retreat, day turns to night a Wolfcastle stares at his shoes and finally concludes that they don't even ''have'' laces.
-->'''Wolfcastle:''' On closer inspection, these are loafers.
* One episode of ''WesternAnimation/{{Futurama}}'' stuck Fry between a jealous Zoidberg and a lovestruck cephalopodian alien.
-->'''Dr. Zoidberg:''' Fry. I challenge you to "clawplach".
-->'''Fry:''' English, please?
-->'''Dr. Zoidberg:''' A fight to the death.
-->'''Edna:''' And if you survive, we'll make sweet love.
-->''(Fry thinks it over for a second, then makes a bloodcurdling scream of terror.)''
** Though that one's less a delayed reaction and more weighing which option would be the LesserOfTwoEvils and realizing neither one's good.
* ''WesternAnimation/GeorgeOfTheJungle'' - more than once, George would suddenly laugh at a joke he'd heard minutes, maybe hours, before.
* In an episode of ''WesternAnimation/KimPossible'' Ron tries tries to rush Kim and her [[MirrorMoralityMachine temporarily-good nemesis]] to a movie:
-->'''Kim:''' Tempting, but I promised Shego we're go get our eyebrows waxed.\\
'''Ron:''' Okay, but we're going to have to -- [{{beat}}] You ''wax'' your ''eyebrows?'' What's that about?\\
'''Kim:''' Forget I mentioned it.\\
'''Ron:''' Done!
* ''WesternAnimation/FamilyGuy'':
-->'''Peter''': So did your therapist figure out what the problem was?
-->'''Brian''': Yeah. He thinks I'm in love.
-->'''Peter''': Oh my God...[[CaptainObvious you can]] ''[[CaptainObvious talk]]''!
* On ''WesternAnimation/JimmyTwoShoes'', when Lucius wakes up after a day where everyone was pulling revenge pranks, he concludes that everything is back to normal. Then a [[TalkingAnimal talking bird]] greets him through the window with a pleasant "Good morning." Lucius returns it and walks off...then dashes back to the window when he realizes how wrong that is in Miseryville.
* In ''WesternAnimation/DanVs'' "The Animal Shelter," Chris picks at a meatloaf Dan made while Dan describes why he needs to take revenge on an animal shelter. When Dan mentions it involves a poisoned meatloaf, Chris continues to eat the meatloaf for three more {{beat}}s before what Dan just said sinks in.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Fluttershy has this when she sees Princess Luna (formerly Nightmare Moon) on [[AllHallowsEve Nightmare Night]].
-->'''Twilight''': Fluttershy, it's me, Twilight.
-->'''Fluttershy''': It is you. Ah, Nightmare Moon. [beat] Nightmare Moon!
* Classic one done in ''WesternAnimation/FrostyTheSnowman'', with the traffic cop that meets Frosty...
-->'''Cop''': Dumb snowmen. When they first come to life, they don't know ''nothin''.
-->({{Beat}} for about two and a half seconds)
-->'''Cop''': ''Come to life?!?!'' (accidentally swallows whistle)
** Done again in the sequel, where the same cop seems to be used to Frosty, and then meets his new wife...
-->'''Cop''': Well, isn't that sweet. A snow wife.
-->({{Beat}} for about two and a half seconds)
-->'''Cop''': ''A snow wife?!?!'' ([[CallBack accidentally swallows whistle]])
* In the ''WesternAnimation/KingOfTheHill'' episode "The Texas Skilsaw Massacre" Dale doesn't scream until ''after'' he sees that Hank accidentally cut his finger off with the titular skilsaw.
* In an episode of ''WesternAnimation/TheClevelandShow'', a gang of troubled teens Cleveland has been watching tells him that the "cookies" he took from a rivil gang were actually cocaine and that they're coming for him. Cleveland seems to take it pretty well, the he's suddenly running around the room squealing like a pig.
* One ''WesternAnimation/{{Popeye}}'' cartoon had Olive do this when she answered the phone.
-->'''Olive''': Hello? Oh, you say I won a sweepstakes? That's nice. [Resumes what she was doing for a few seconds, and then...] SWEEPSTAKES?!
* An episode of ''WesternAnimation/HiHiPuffyAmiYumi'' has Yumi getting annoyed with Ami's strict scheduling, so she sets Ami's alarm clock to wake her up later. This results in Ami's reaction time to certain events being lengthened, such as getting hit by a frisbee and being told a joke.
* In the ''WesternAnimation/SpongeBobSquarePants'' episode "Home Sweet Pineapple", it takes Patrick a full 15 seconds after seeing that [=SpongeBob=]'s house is missing and the latter explaining what happened to it for him to exclaim "Hey, [=SpongeBob=], your house is gone!"
** Later [=SpongeBob=] stays the night in Squidward's house, and it takes a half-asleep Squidward 48 seconds to realize this just happened.
* Pulled on Sokka in ''WesternAnimation/AvatarTheLastAirbender'' while Katara and Aang were critizising his (poorly drawn) rendition of Appa.
-->'''Toph:''' [[DisabledSnarker It looks]] ''[[DisabledSnarker just]]'' [[DisabledSnarker like him to me.]]
-->'''Sokka:''' Thank you, I worked really hard on- Why do you feel the need to do that?
** She would also get almost EVERYBODY while on a high speed desert search.
--->'''Toph:''' THERE IT IS!
--->'''Everybody else:''' *excitedly stare in the direction she's pointing, then catch on all at once.*
--->'''Toph:''' That's what it will sound like when one of you SPOTS it. *grins and waves her hand in front of her [[spoiler: blind]] eyes.

* The Guinness Book of World Records lists the man with the slowest reaction speed ever recorded: 20 seconds. He demonstrated on TV by being ''punched in the face''. Twenty seconds later, he felt the pain and reacted accordingly.
* Pokemon was made in 1996, and PETA realized they're against it circa 2012.
** Ironically, when they finally reacted, it was with a badly made parody of the ''only'' [[PokemonBlackAndWhite entry in the Pokemon series]] that actually questioned the ethics of Pokemon battling. And to add insult to injury(?) the villains could be viewed as a very thinly-veiled parody of PETA.
