->''"Ten more years and PETA should realize this exists."''
-->-- '''[=BananaMammoth=] in response to [[http://www.youtube.com/watch?v=yhuMLpdnOjY this little ditty]] by Music/TomLehrer'''

AliceAndBob are having a conversation. During the conversation, Bob says or does something that you'd think would induce a reacting in Alice; 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. Bonus points if the character walks off-screen, then yells something said out loud and races back.

TruthInTelevision, obviously. People with slower reaction times tend to take longer to realize things. Also often tends to happen when people [[NotListeningToMeAreYou aren't really paying attention to things they should be]] before [[DoubleTake suddenly realizing the importance of what they just witnessed]].

See subtrope LateToThePunchline when Alice makes a joke, StealthPun or StealthInsult on the expense of Bob and he doesn't get the true meaning right away. Compare ITakeOffenseToThatLastOne and ComebackTomorrow. Compare DelayedOhCrap and ExplainExplainOhCrap. See YouAreAlreadyDead for the combat version. See RepeatedCueTardyResponse when trying to set up a cue with someone but they missed the cue and they have to repeat it until they get it. Often follows a {{Beat}}.

* ''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/MonthlyGirlsNozakiKun'', 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.
* In ''Manga/MyMonsterSecret'' Chapter 98, the protagonists are playing dodgeball against their teacher (or more accurately, [[DodgeballIsHell they're trying not to get slaughtered by her]]). While they're plotting their strategy, Sakurada says "If we win this, I think I'll [[LoveConfession confess my feelings to Komoto-sensei]]." The planning continues for another panel before everyone starts saying things like "I feel like I just missed something" and they ask Sakurada to repeat himself; he admits that he's [[HotForTeacher got a crush on their teacher]] and [[BestHerToBedHer wants to confess if they win]], prompting a nine-person BigWhat

[[folder:Comic Books]]
* From ''Broom-Hilda'', the title 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 ''ComicBook/GrooTheWanderer''
-->'''Someone:''' Groo, you can not understand this, since you are slow of mind.\\
'''Groo:''' ''[pages later]'' ...What he mean "slow of mind"?
** In one extreme case, he utters this phrase in response to a ''childhood flashback.''
** Extreme in a different way: he once calls ''himself'' "slow of mind" and then later wonders what he meant by it.

[[folder:Comic Strips]]
* 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:Fan Works]]
* Ichigo does this in ''[[https://m.fanfiction.net/s/5665175/12/ Red Duty, Black Honor]]'' when Rukia talks to him while he's doing paperwork and informs him they're getting married (and keep in mind they're not even ''dating'' at this point). Kira, meanwhile, watches it all unfold nearby.
-->'''Ichigo:''' Now, Rukia, what did you just say?\\
'''Kira:''' ''Five, four...''\\
'''Rukia:''' I said, we're getting married. You and I.\\
'''Kira:''' ''Three, two...''\\
'''Ichigo:''' That's what I thought you said.\\
'''Kira:''' ''One...now.''\\
'''Ichigo:''' ''Are you out of your mind?!''
* ''WebVideo/DragonBallAbridged'':
** It 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.\\
'''Gohan:''' Wait, didn't you--\\
'''Piccolo:''' Give him a minute.\\
''[beat, beat, beat]''\\
'''Dordabo:''' ...Hey!
** The first speaking role of a Kanassian 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.
** During the Namek arc:
-->'''Freeza:''' Why aren't the [[EliteMooks Ginyus]] showing up?! Oh, they're dead. [{{beat}}] ''WHY ARE THEY DEAD?!''
* 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.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''[[https://www.fimfiction.net/story/194909/the-queens-secret-crush The Queen's Secret Crush]]'', Rarity is royalty and her bodyguard Twilight is her lover. Her teenage sister Sweetie Belle finds out about her crush on somepony and tries to find out who she is. Rarity won't directly tell her but ''heavily'' implies it's Twilight Sparkle. She events starts blatantly flirting with Twilight, however Sweetie Belle doesn't catch on.
-->''"Can't think of anypony who fits the description except for Twilight." Sweetie shrugged and looked back at the two mares. "I'll figure it out, though! Apple Bloom knows everypony in the castle, so she might help. Anyway, see you for dinner, Sis! Bye, Twilight!"''
-->''The second Sweetie Belle had left the room, Twilight turned to look at Rarity. "I'm really sorry to say this, but the princess is really dense. We couldn't have been more obvious even if we had put a sign that sai--"''
-->''Rarity put her hoof on top of Twilight's mouth, silencing the unicorn. "Now, now, Twilight. Wait a moment, will you?"''
-->''A few minutes later, a high pitched "OH MY GOSH" rang through the halls of the castle, followed by the sound of running hoovesteps. Sweetie Belle's head suddenly poked into the room, her eyes wide as saucers.''
-->''"Are you two..."''
-->''"Yes, dear."''
-->''"For how long have you..."''
-->''"A while now, darling."''

[[folder:Film -- Animation]]
* In ''Disney/BeautyAndTheBeast'' After the Beast releases Belle from the Castle and informs Cogsworth.
-->'''Cogsworth:''' Well, Your Highness, I must say everything is going just swimmingly. I knew you had it in you, ha ha!\\
'''Beast:''' ''[sadly]'' I let her go.\\
'''Cogsworth:''' ''[chuckles]'' Yes. Splendid...[[OhCrap You]] ''[[BigWHAT WHAT?!]]'' How could you do that?!\\
'''Beast:''' I had to.\\
'''Cogsworth:''' B-But why?\\
'''Beast:''' Because...I love her.
* In ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', after Spike is exposed to Fluttershy's magic drained out of her by the device, Human!Twilight asks him if he's okay. Her initial reaction is relief when he tells her "Um... I think so." And ''then'' she freaks out as she realizes her pet dog just talked.

[[folder:Film -- Live-Action]]
* In ''Film/DeathNote'', Ryuk wonders why Light was ignoring him. When Light in the convenience store explained to Ryuk that the former has a feeling that he's been watched via CCTV which means no Apples for Ryuk, it took a few seconds for the Shinigami to realize what Light meant and reacted in [[BigNo sorrow]].
-->'''Ryuk:''' Nooooooooo!!!
* From ''Film/DumbAndDumber'', in a scene where Lloyd finds a newspaper clipping of the Moon Landing (over 25 years before the film was made):
-->'''Lloyd:''' I can't believe it! We landed on the Moon!
* In ''Film/TheFifthElement'', a cop car is getting lunch from [=McDonald's=]. The driver informs dispatch that they're on their way in pursuit of Korben's cab, before quietly adding as soon as they're done with lunch.
-->'''Cop:''' I'm too old, too tired, and too hungry to go chasing some hot rod. ''[interrupts his colleague who's flirting with the drive-thru attendant]'' And I'm definitely too thirsty.
-->'''Korben:''' LOOK OUT!!!
-->''[Korben sideswipes the patrol car, causing the cop to spill his drinks and knocking over their Big Macs]''
-->'''Cop:''' ''[after a moment]'' ... whoa.
* One of the many {{Running Gag}}s in ''Series/FTroop'' involved Cpl. Agarn making a snide comment about their current situation, like "It's a shame we can't get someone to sing in his place." The other person, realizing that this is actually a good idea, says "Agarn, I don't know why everyone says you're so dumb!" Later, usually after the next scene change, Agarn suddenly shouts "''Who'' says I'm dumb?"
* 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.
* 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.
%%* Creator/LaurelAndHardy: Stan and Ollie are usually also very slow to realize what's going on around them.
* 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. [[Series/MysteryScienceTheater3000 Mike Nelson]] refers to it as "Delayed reaction syndrome".
* Performed twice by Creator/JackLemmon's character Daphne in ''Film/SomeLikeItHot'':
** At the beach when he glances at Joe in his millionaire costume, he walks away only to stop in his tracks and return to have a closer look.
** When he stashes away Osgood's wristband case, he stops after a second and reopens it to notice that the wristband is gone.
* ''Film/InspectorGadget'':
-->'''Penny’s Friend''': Is Penny with you, Mr. Gadget?\\
'''Gadget''': No. You can call her at home.\\
'''Friend''': I called her at home. There was no answer. I’ll try again.\\
'''Gadget''': OK. ''[hangs up, {{Beat}}]'' [[BigWhat What does she mean there was no answer?]]

* 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 [[Creator/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.
* Played for drama in ''Literature/TheGirlFromTheMiraclesDistrict'', when Nikita flies into a berserker rage the night after the inciting incident, which is to say at the worst possible moment.
* 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:Live-Action TV]]
* In an early episode of ''Series/TheBigBangTheory'', Raj gets drunk and talks to Penny about his inability to talk to women. Leonard is about to mention this, but Howard interrupts, wanting to see how long it takes him to figure it out. Penny ends up telling him.
-->'''Sheldon''': And now we'll never know.
* 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.
* ''Series/DoctorWho'':
** In [[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 "No, I'm sorry. Did he say he was going to 'change what it means to be human'?"
** The Doctor gets another one in [[Recap/DoctorWhoS31E12ThePandoricaOpens "The Pandorica Opens"]] with regards to [[spoiler:the [[BackFromTheDead 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. ''[walks out of the room carrying two Cyber-guns]''\\
''[a [[DramaticDrop clang]] is heard, and the Doctor slowly walks back in, staring at [[spoiler:Rory]]]''\\
'''The Doctor:''' ''[pokes [[spoiler:Rory]] in the chest]'' Hello again.
** [[Recap/DoctorWhoS36E1ThePilot "The Pilot"]]: New companion [[TomboyishName Bill]] Potts takes quite some time to realize that the TARDIS is BiggerOnTheInside, instead thinking it's a "knock-through"[[note]]the box is hiding a hole in the wall to a larger room[[/note]]. Of course, she ''has'' known the Doctor for months by then and in all that time has only ever seen the TARDIS parked in the corner of the Doctor's office flush in a corner. She only catches on when she exits in a completely different location.
* ''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.
* ''Series/{{Friends}}'':
** In "The One Where [[spoiler:Rachel]] 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.
* 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.
* ''Series/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/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 realize 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/{{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.
* 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?
* 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/OurMissBrooks'': Mr. Conklin does this often for comedic effect.
* ''Series/{{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?
* In the ''Series/{{Seinfeld}}'' episode "The Wallet", when Kramer lights a Cuban using Jerry's stove, he also lights his hair on fire. It takes him a good ten seconds before he screams.
* 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??
* 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.
* 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.
* 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?
* ''Series/WhoseLineIsItAnyway'' has [[ExactlyWhatItSaysOnTheTin Delayed Reaction]] [[http://www.youtube.com/watch?v=WNvGJO2AaDc Man]].

[[folder:Puppet Shows]]
* 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?!?

* 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 Website/FourChan 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.
* In ''Persona Q: Shadow of the Labyrinth'', on the P3 side, Rei eats Yukiko's horrible cookies and comments that it was fine. But only after she notices that Zen ate the cookies and passed out standing up, the cookies take effect and she passes out suddenly.

[[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.
* In ''VisualNovel/{{Danganronpa}}'', upon TheReveal that [[spoiler: Chihiro Fujisaki was actually male rather than female]], it takes a little while for it to sink in with Hifumi.
-->'''Hifumi:''' (calmly) Ah, I see. So [[spoiler: "she" was actually a he]]. Interesting. Thank you for confirming this fact.\\

[[folder:Web Comics]]
* A few instances of this occur in ''Webcomic/ExterminatusNow'' -- like triggering the decoy SelfDestructMechanism.
-->'''Virus:''' Damnit!\\
'''Lothar:''' Ha, I win! ...Wait, shit.
* 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.
* In ''Webcomic/TheWhiteboard'', Sandy's gotten quite a bit quicker over the years, but right after she was hired, it took her a bit to catch [[https://web.archive.org/web/20160906114552/http://www.the-whiteboard.com/autowb434.html this gag.]]

[[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.
* From WebVideo/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?!'''''"
* Among other jokes about Caboose's lack of intelligence in ''Machinima/RedVsBlue'', he will occasionally slow down mentally. He once thought an Elite was using telepathy because his mind was only registering the alien's words ''after'' it stopped talking. Another time it took him a few minutes to realize that Agent Washington had pulled a StealthHiBye. And when Grif was speeding around on an out-of-control speed enhancement, he said, "Hey, Grif." several seconds after Grif raced past him.

[[folder:Western Animation]]
* ''WesternAnimation/AmericanDad'' demonstrates this trope in the episode where Stan [[ForgottenAnniversary forgets his anniversary]].
* ''WesternAnimation/AvatarTheLastAirbender'':
** Pulled on Sokka when Katara and Aang are 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 blind eyes]''
* In an episode of ''WesternAnimation/TheClevelandShow'', a gang of troubled teens Cleveland has been watching tells him that the "cookies" he took from a rival gang were actually cocaine and that they're coming for him. Cleveland seems to take it pretty well, then he's suddenly running around the room squealing like a pig.
* 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.
* ''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]]''!
* ''WesternAnimation/FrostyTheSnowman'':
** Classic one 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?!?!''' ''[[[ContinuityNod accidentally swallows whistle]]]''
* ''WesternAnimation/GarfieldAndFriends'':
** One ''U.S. Acres'' segment dedicated to [[NoFourthWall discussing animation tropes]] has 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!?"
* 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 five seconds later. This results in Ami's reaction time to certain events being lengthened, such as getting hit by a frisbee and [[LateToThePunchline being told a joke]]. Briefly inverted later in that episode when Yumi was trying to set the alarm clock right but set it a few seconds ahead. This results in Ami [[PreemptiveDeclaration saying "Gesundheit" to a sneeze Yumi was about to have]].
* 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 [[CrapsackWorld Miseryville]].
* ''WesternAnimation/{{Kaeloo}}'':
** In Episode 81, [[CatsAreMean Mr. Cat]] offers to demonstrate the ancient Egyptian technique of removing the brain through the nostrils on [[TheDitz Stumpy]], but then says he can't because Stumpy probably doesn't have a brain for him to remove. Stumpy concurs that he must be right, and Mr. Cat gets up and leaves. After he leaves, Stumpy finally realizes that he was insulting him.
** In another episode, Stumpy is granted SuddenIntelligence and starts inventing stuff. Soon, he decides to make a bomb, and [[InadvertentEntranceCue as soon as he mentions it]], [[HarmlessVillain Olaf]] shows up and demands that Stumpy give him the bomb. Stumpy asks him to pay for it, and Olaf starts looking through his money before [[GenreSavvy realizing that]] Stumpy is supposed to be TheDitz and asking why he is being so smart.
** In Episode 65, Kaeloo gets angry at Mr. Cat and starts to look for him. In this episode, everybody has {{Full Body Disguise}}s of everyone else, so Mr. Cat dresses as Pretty, tells Kaeloo that he went the other way and walks off. Kaeloo thanks him, but only after he's gone does she realize that the voice she heard was clearly Mr. Cat's.
** In the episode "Let's Play Tennis", Stumpy is sitting in a tennis umpire chair. It takes him several minutes until he realizes that he's very high up... and a few more seconds to remember that he has acrophobia.
* 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!
* 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.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** "[[Recap/MyLittlePonyFriendshipIsMagicS2E4LunaEclipsed Luna Eclipsed]]": Fluttershy has this reaction 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!
** "[[Recap/MyLittlePonyFriendshipIsMagicS2E10SecretOfMyExcess Secret of My Excess]]": Rarity has one upon first hearing Spike intends to eat the Fire Ruby.
--->'''Rarity:''' Is that a Fire Ruby? That must be at least 20 carats! No inclusions, pristine facets...\\
'''Spike:''' And totally delicious.\\
'''Twilight:''' Uh, you guys don't mind?\\
'''Rarity:''' Oh, of course. I just came by to see if you had any books on historical fashion. Did you say "delicious?"\\
'''Spike:''' Sure did!
** In "[[Recap/MyLittlePonyFriendshipIsMagicS2E22HurricaneFluttershy Hurricane Fluttershy]]", Fluttershy keeps flying around in circles even after the tornado has disappeared.
** "[[Recap/MyLittlePonyFriendshipIsMagicS4E19TradeYa Trade Ya!]]". Twice by Rainbow Dash:
*** After being turned down so many times for trying to trade her horseshoe, one pony actually asks for it, which Rainbow takes a moment to realize.
*** When she finally gets the Orthros, only for the book's owner to say that she doesn't want an Orthros anymore, Rainbow freezes with her manic grin still plastered on her face. Several seconds later, she reacts by fainting.
** "[[Recap/MyLittlePonyFriendshipIsMagicS4E9PinkieApplePie Pinkie Apple Pie]]": When the Apples are bickering with each other for their misfortunes.
--->'''Apple Bloom:''' There wouldn't have been an overboard if Big Mac hadn't overpacked the jalopy!\\
'''Big Macintosh:''' Eeyu— Hey!
* One ''WesternAnimation/{{Popeye}}'' cartoon had Olive do this when she answers 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?!
* ''WesternAnimation/{{Rugrats}}'' combines this with a NonSequiturThud as Angelica and Susie are competing to see who's better. One of the competitions is to see who can jump farther off the swing. Angelica does, but lands on her face.
-->'''Angelica:''' I did it! I jumped off the swings farther than you! Now all I gotta do is beat you a million-bazillion more times and... gee, what pretty colors!
* On ''WesternAnimation/SamuraiJack'', the penultimate episode reveals that [[spoiler:Ashi was [[MadeOfEvil created from Aku's essence]].]] In the final episode, [[spoiler:when Jack goes back to his original time period and destroys Aku in the past, Ashi inevitably disappears from existence. Where most characters in her situation would disappear almost immediately after their progenitor's destruction, she doesn't disappear until what was likely several ''hours'' later.]]
* ''WesternAnimation/SpongeBobSquarePants'':
** In the episode "Home Sweet Pineapple", it takes Patrick 16 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.
** In "Ugh", [=SpongeGar=] and Patar put their hands in their recently-discovered fire for a good 10 seconds before screaming in pain.
* ''WesternAnimation/StevenUniverse'': The episode "Off Colors" introduces the outcast Gem Padparadscha, who has this as a tic; unlike a regular Sapphire, who can predict the future, Padparadscha can only predict things that have just happened, and usually when she blurts out these visions, they sound like {{Non Sequitur}}s.
* ''WesternAnimation/TeachersPet'':
** Spot does this when he finds out why Moby and his spouse Charlotte can't go home to his human family:
--->'''Moby''': ...Time for our family to be born.\\
'''Spot''': Uhh... run that by me one more time?\\
'''Charlotte''': I'm about to have puppies.\\
'''Spot''': Ohh; that's nice. She's about to have puppies... (He walks out frame for a second and then zooms back into the picture) PUPPIES?!
* ''WesternAnimation/TomAndJerry'':
** Happens often with Tom, 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.
* Spud in ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' has a delayed reaction to everything, including pain. In "Brazilian Pain Forest", his hand gets bitten by several ants, and it takes him over two hours to realize the pain. His team partner Rock is able to take full advantage of this in future episodes, as he knows exactly when the pain will register. This makes things difficult for them in Finland, when Spud gets bitten by a seal while trying to cross an ice floe.
* ''WesternAnimation/WileECoyoteAndTheRoadRunner'': Wile E. Coyote usually realizes very late that he's walking on thin air. Once he does he falls down.

[[folder:Real Life]]
* 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.
* ''Franchise/{{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'' entry in the ''Pokémon'' series (''VideoGame/PokemonBlackAndWhite'') that actually questioned the ethics of Pokémon battling. And to add insult to injury(?) the villains could be viewed as a very thinly-veiled parody of PETA.
-> '''Groo''': What did he mean, slow of mind?
