[-[[caption-width-right:300:[[IronicEcho So don't just sit there, slack-jawed, buggy-eyed...]]]]-]

->''"I've achieved 'exasperating,' and I've achieved 'eye-popping'. ''(THONK!)'' '''All right!!! 'Jaw-dropping'!!'''"''
-->-- '''ComicStrip/{{Garfield}}''', reacting to Jon Arbuckle doing this, after seeing Garfield had torn up his furniture

Most frequently observed in WesternAnimation, though it also occurs in other media as well. A character becomes surprised or shocked, and their jaw drops comically, oftentimes with the [[StockSoundEffects sound of a cash register]] for the comedic cherry on top. This is done to ridiculous extents in some cases (where the jaw drops to the floor and sometimes even an OverlyLongTongue rolling out, as seen with Genie in the image on the right), but also sometimes within a reasonable human limit (as seen with Jafar).

On occasion, another character will reach over and close the dropping character's jaw.


* An ad for mobile phone plans that would "really make your jaw drop" was accompanied by a man's jaw dropping to ever-increasing CGI-lengths as he listened to each new benefit.
* There was once an [[https://www.youtube.com/watch?v=proTtfmGpK8 ad for the Ford Ka]] featuring a jaw drop.

[[folder:Anime & Manga]]
* ''Manga/AzumangaDaioh'': Used as Mr. Kimura's default expression, as it's rare to ever see him with his mouth ''closed''.
* In ''LightNovel/{{Bakemonogatari}}'', Araragi takes a moment to really look at the [[CatGirl Bakeneko]] (who is possessing Hanekawa). As he takes in all the details -- the long white hair, the twitching [[UnusualEars cat ears]], the bare shoulders, the [[BuxomIsBetter large breasts]] [[FanService bulging out of the half-unbuttoned pajamas]], the cat-like way she licks the back of her hand -- his draw drops so hard it ''cracks the concrete.'' [[http://www.youtube.com/watch?v=nbNigEVrh2I You may have the same reaction.]]
* Hideki of ''Manga/{{Chobits}}'' drops his jaw in four stages, each time making a sound like a squeaky hinge, when Chi points at a want ad for a dominatrix and asks whether it's a job she could do.
* In ''Anime/DigimonAdventure02'', Daisuke (Davis), V-mon (Veemon) looks Patamon digivolving to Angemon
* In ''Anime/DigimonTamers'', Jenrya (Henry), Ruki (Rika), and their partners do this when they realize that Dukemon (Gallantmon) is Takato fused with Guilmon, though compared to other anime, their expressions are much tamer (no pun intended).
* ''Anime/DragonBallZ'': It happens to Krillin after being dumped by his ex-girlfriend (in one of the anime fillers).
** Back in the original ''Manga/DragonBall'' era's second arc, Master Roshi/"Jackie Chun" had a pretty good one when Goku avoided a ringout by helicoptering in with his tail..
* ''Manga/FullmetalAlchemist''
** The addition of one of these to a scene near the end of ''Brotherhood'' manages to make a moment that is already [[CrowningMomentOfAwesome awesome]] in the manga even ''more'' awesome. Because the jawdropper is [[spoiler:''[[{{God}} Truth]]'']].
** Greed after [[spoiler: Edward decides to '[[InsistentTerminology work]]' for him]].
** Alex and Olivier Armstrong also do this after witnessing [[spoiler:Izumi toss Sloth around like a ragdoll]].
* ''Anime/TengenToppaGurrenLagann'' has this in episode 13. Everyone on the team does this when they see Simon and Boota ravenously devouring the vast array of food prepared by LethalChef and otherwise perfect girl Nia, having just sampled the food themselves.
* Dedede and Escargon from ''Anime/KirbyOfTheStars'' does this after catching a glimpse of Fumu-tan of the Stars.
* Chamo the ermine from ''Manga/MahouSenseiNegima'' does this when he sees Negi run out of magic, the Giant Oni is standing in front of him, and the powerhouse mage behind him gets out of his bind.
* ''Manga/MakenKi'': Minori has a knack for leaving onlookers shitfaced [[ThisCannotBe in disbelief]], due to [[BadassAbnormal how freakishly strong she is:]]
** She left everyone slackjawed, near the end of the Venus Arc, by physically ripping apart one of Martha Minerva's dimensional barriers. A feat that ''should have been'' impossible, since Minerva is an '''SS rank''' Maken user.
** During her fight with Ouken Yamato (chapter 42), she punched him through a cliff wall and out the other side, which split the rockface in half and left Takeru incredulous. Then she stunned Miyabi when she unleashed "Ginko Muro" on Ouken, causing Miyabi [[ThisCannotBe to fear Ouken]] might've lost.
* Occasionally done in ''Manga/{{Naruto}}'' when Kishimoto briefly uses the "comedic" wacky art style instead of his more realistic one.
* ''Manga/OnePiece'' has enough to justify its own page.
** In the first half of the series, this is the general reaction when Luffy reveals his [[RubberMan Gum-Gum powers]]: Alvida and crew, Coby, Zoro, Nami, Buggy and crew, Carrot, Pepper, Onion, Usopp, Kaya, the Black Cat Pirates, Sanji, Don Krieg's crew... the list goes on.
** Some of Alvida's pirates have this reaction when Luffy bursts out of a wine barrel, and then casually asks who they are.
** Alvida, Coby, and all of her crew do this when Luffy calls Alvida fat (or rude, or ugly, depending on the translation): her BerserkButton.
** Axe-Hand Morgan, Helmeppo, and all present Marines when Luffy accidentally breaks Morgan's giant statue of himself.
** Also done by Buggy's crew and Nami when Luffy presses his Berserk Button: "BIG NOSE!"
** Johnny and Yosaku have an epic one when they see that Arlong bit a stone pillar…and the pillar breaks beneath his teeth. Usopp gets one, too, but nowhere near as epic.
** When Nami leaves her hometown to go with the Straw Hat Pirates, she rushes through the crowd, assembled to see the Straw Hats off, without stopping or giving anyone a decent opportunity to bid her farewell, and leaps from the port all the way to the ship, which had already gotten some distance away. Then she lifts her shirt, and countless wallets fall to the ground…yeah, she ''pick-pocketed the entire village.'' Cue their Jaw Drop.
** Every single member of Buggy's crew after Luffy's miraculous rescue.
** Mr. 5 has this reaction right before Zoro [[OneHitKO one-shots]] him. Vivi has this reaction immediately afterwards. And then Carue has this reaction a few moments later, when Nami comes out of nowhere and one-shots both Luffy and Zoro.
** Vivi tells Luffy, Zoro, and Nami not to ask her about the identity of the boss of Baroque Works, because if she tells them, they'll be in danger too. [[SammysGlassEye Then she lets it slip.]] Nami and Vivi have this reaction while Zoro says "YouJustHadToSayIt".
** On Little Garden, when Sanji casually reveals to the others that they don't actually have to wait around for a year for the log pose to reset, because he intercepted an Eternal Pose to Alabasta (which is exactly where they want to go). Cue ''giant'' jaw drop from the ''entire'' rest of the group (Luffy, Zoro, Nami, Usopp, Vivi, and Carue, a ''duck''), which in turn causes Sanji to SweatDrop.
** In Alabasta, Luffy performs a Gum-Gum Rocket to get to a restaurant, because he's hungry…as usual. He flies into Smoker, knocking him and Portgas D. Ace through at least fifteen walls before he asks the chef for food. Everyone in the restaurant has this expression, not just because of his DynamicEntry, but because he just sent Ace flying, and Ace is a very high-ranking member of the [[TheDreaded Whitebeard Pirates]]. And their fear probably would have been justified if Ace wasn't his brother.
** God Enel (Eneru) is always calm and composed...until he realizes [[ShockAndAwe his powers]] don't work on [[RubberMan Luffy]]. [[http://static.tvtropes.org/pmwiki/pub/images/onepiecejawdrop.jpg Cue FULL PAGE Jaw Drop]].
** The reaction of the entire Franky Family and the Galley-La Foremen when Luffy and Zoro create a gaping hole in the Aqua Laguna (a tsunami) large enough for their sea train to go through, when their best efforts only made splashes.
*** A bit later, they have this reaction again when Zoro bisects a pair of train cars in front of them. The government agents in said train cars join in the Jaw Drop and the BigWhat.
** Oimo has one after he's been tricked into hitting Kashi with his club, knocking him out.
** Done ''frequently'' with Spandam, in his equally frequent OhCrap moments.
** All of the Marines and Agents on Enies Lobby, along with Spandam and Robin, have this reaction when the Straw Hats shoot the World Government's flag: a declaration of war.
** The reaction of everyone present when Robin uses her powers to squeeze Franky's testicles.
** Although it wasn't on a full page, Perona pretty much had a very similar expression as Enel when she realized her powers (which makes people feel extremely negative about themselves) can't work on Usopp.
** Luffy, and later Zoro, Usopp, Chopper, Brook, and Nami to a lesser extent have this reaction when they see Duval's face.
** When Luffy attacks Saint Charloss for shooting Hachi[[note]]Charloss is a World Noble, who are practically the AristocratsAreEvil trope incarnate, and the price for harming them in any way is being hunted down by a Marine Admiral. Why is that bad? Anyone with enough power to hold the title of Admiral is considered TheDreaded; most pirates would run away screaming at the mere sight of one.[[/note]] the only ones in the entire building who don't have this reaction are the other Straw Hats, the other World Nobles (though they're stunned, too), and Trafalgar Law and Eustass Kid, both of whom smirk.
** Everyone in the Kuja Tribe except the leader, Boa Hancock, does this when Luffy [[OneHitKO one-shots]] Bacura.
** Ivankov, Buggy, Galdino (Mr. 3), and hundreds of Marines and pirates have this reaction when Luffy starts talking back to Whitebeard, and then shouts at his face, "I'M GOING TO BE KING OF THE PIRATES!" For dozens, if not hundreds, of the pirates and Marines, this justifies ATruceWhileWeGawk.
** In Chapter 731, Luffy [[WhamEpisode mimics the audience's reaction]] with a huge, Enel-like jaw drop that once again fills the entire page. We don't see what he sees, but we're told what it is through a very-telling WhamShot: [[spoiler: '''''Sabo''''', who is actually still alive.]]
** Rocinante, a.k.a. Corazon, does this when Law first refers to him as "Cora-san".
** Diamante has this reaction in Chapter 776, mixed with OhCrap, when he sees that Kyros is unfazed by an attack that could take out an army. Underestimating him was a fatal mistake.
** And ''nothing'' can be said about the epic, collective jaw drop all of Dressrosa has in Chapter 778 after [[spoiler:'''''[[PersonOfMassDestruction Zoro slices the mountain-sized Pica to bits]]''''']].
* In Episode 21 of ''Anime/OsomatsuSan'', the Sextuplets do this after Kamimatsu reveals that he has naturally started a job for the family.
* ''Anime/{{Pokemon}}''
** Ash does this when he realizes that he's won against Sabrina in their gym match when Haunter gets her to laugh, which, due to a telepathic bond with her Kadabra, makes it laugh, too.
** Brock's Ludicolo [[http://www.serebii.net/anime/pictures/houen/382ps11.shtml has an epic jaw drop]] after his Mawile crush dumps him for a Psyduck.
* Jaden Yuki on ''Anime/YuGiOhGX'' does this while turning his face square.
* In the episode "The Steel Bison", ''Anime/ZoidsChaoticCentury'' has the ''Blade Liger'' of all things doing this with a SweatDrop when it's accidentally targetted by the [=DiBison=] along with the enemy targets before firing a BeamSpam.

[[folder:Comic Book]]
* Phoney Bone does this in ''Comicbook/{{Bone}}'' when Lucius outsmarts him at the Big Cow Race by putting the deed to his tavern on Gran'ma Ben... [[HoistByHisOwnPetard At 100:1 odds that Phoney had arranged for after fooling everyone else into thinking she couldn't win]].

[[folder:Comic Strips]]
* ''ComicStrip/{{Candorville}}'' has an unusual variant in which characters' jaws unroll like carpets, lying flat across surfaces. [[http://candorville.com/2010/10/08/something-good-5/ This is a good example]] of the phenomenon.
* In response to the above quote, Jon did this in [[http://www.garfield.com/comic/1993/12/04 this strip]] of ''ComicStrip/{{Garfield}}''.

[[folder:Fan Works]]
* ''Fanfic/BatmanBeyondRevisited'': Jake’s reaction to Inque’s elegant dress.
* In ''ComicBook/{{Supergirl}}'' fanfic ''Fanfic/HellsisterTrilogy'', this is Kara's reaction when she finds out her old enemy Satan Girl has returned.
-->"Now--here I am," she said, taking a seat at the table. "I see you've got the Fatal Five out again. But you could probably handle them without me. And I've been brain-scanned twice in the last few minutes. It sounds like something's coming up for me, specifically. Why did you summon me?"\\
"Because of this," said Brainiac, and thumbed the controller again. The image of a masked woman came up on one of the holoscreens.\\
Supergirl dropped her jaw.\\
"Her!" she said, after she found her voice. "Great Rao, after all these years... her!"
* Koizumi in the ''LightNovel/HaruhiSuzumiya'' fanfic ''Fanfic/KyonBigDamnHero'' after Kyon commented he (that is, Kyon) [[spoiler: was set in an ArrangedMarriage with Tsuruya.]]
* ''Fanfic/LuffysRenewedAdventure'': Frequent, of course, even if you don’t count the ones borrowed from canon.
** When Luffy performs the aforementioned Groin Attack, Coby has one of these, but Zoro is too busy laughing his ass off to do the same.
** When Luffy makes a deal with Morgan to give him a boat and let him leave the island if he wins…and then stands still and does nothing, everyone apart from Morgan does this. Then they have another one when he hits Luffy with his axe, and the axe shatters.
** Zoro, Nami, and Buggy’s crew all have this response when Luffy survives a direct, point-blank hit with the Buggy Ball without a scratch.
** Johnny and Yosaku have this reaction when Luffy catches the cannonball that Fullbody shoots at them.
** The Krieg pirates and Baratie chefs do this when Gin begins his TheReasonYouSuckSpeech about the crew.
** Everyone present has this reaction when Luffy swallows the [=MH5=] bomb and blows the gas back at Krieg, remaining perfectly unharmed thanks to his AcquiredPoisonImmunity.
* ''[[Fanfic/NewGamePlusOnePiece New Game Plus]]'': Frequent, but then, it ''is'' a One Piece fic.
** When Luffy one-shots one of Alvida’s lackeys, sending him flying through the walls of the ship and out into the horizon, Coby and the other two lackeys have this reaction.
** When Luffy responds to Alvida’s FairestOfThemAll question with the truthful answer of Boa Hancock, Coby gapes at his gall at not answering Alvida. It grows further when he blatantly insults her.
** Helmeppo, Coby, and Ririka have this reaction when Luffy uses his Haki to knock out the Marines flanking Helmeppo. Coby’s continues when he one-shots Helmeppo.
** Morgan’s underlings have this reaction when Luffy insults him and announces his intention to defeat him.
** Buggy’s three lackeys have this reaction when they announce their intention to rob them, and Luffy just laughs. Then they do it again after Zoro cuts one of their swords at the hilt.
** Buggy and his crew have this reaction when Luffy shows off Gear Third, and he only uses half of the normal amount of air.
** Under Even Evil Has Standards, Buggy is appalled at the interest rate Nami charges Luffy for repairs.
** Courtesy of his powers, Buggy’s jaw actually separates from his head when he hears that the Training From Hell that Luffy is putting his crew through was learned through firsthand experience with his grandfather. His crew has this reaction when they learn who said grandfather is.
** Many of the ones watching have this reaction when Luffy protects the Baratie chefs from Don Krieg. Or rather, after he catches all of the bullets that Krieg fires.
** The Baratie chefs have this reaction when Zeff announces that they'll be joining the Straw Hats, followed by cheering.
* Lady Silvermane does this in ''FanFic/{{Whispers}}'' after learning of Princess Luna's betrayal, apparently needing her ''hoof'' to close it.
* Calvin's mom does this in ''Fanfic/CalvinAndHobbesTheSeries'' when she realizes that the canoe (the only way off their camping island) has drifted away.
* In ''WebAnimation/DeathBattle'', this is [[Franchise/{{Transformers}} Starscream's]] reaction to [[WesternAnimation/MyLittlePonyFriendshipIsMagic Rainbow Dash's]] [[SuperSpeed Sonic]] [[EverythingsBetterWithRainbows Rainboom]].
* In ''WebVideo/DragonBallAbridged'', Krillin does this just like in [[Manga/DragonBall the original anime]] as mentioned above. However, this time it isn't because Maron is dumping him, [[spoiler:but because she reveals that she's actually an undercover government agent who pretended to be his girlfriend so she could investigate suspicions of Krillin being guilty of insurance fraud]].
* FanFic/MirrorsImage has one for Rainbow Dash mixed with StunnedSilence when [[spoiler:Chrysalis signs a copy of the latest Daring Do book, revealing herself as the author of the Daring Do series.]]
* In the [[WesternAnimation/TheLegendOfKorra Legend of Korra]] fanfic [[FanFic/BookFiveLegends Book Five: Legends]] this is Bolin's rather understandable reaction to seeing Korra and Asami's BigDamnKiss in the finale.
* In the ''Series/StarTrekEnterprise'' ParodyFic "Farce Contact", T'Pol tells Trip to relax his jaw while giving Vulcan neuropressure. As [[DistractedByTheSexy Trip finds this difficult]] she slips off her top, causing Trip's jaw to drop at the sight of the best Vulcan peaks outside of Mount Seleya.

[[folder:Films -- Animation]]
* In Disney's ''Disney/{{Aladdin}}'', Genie does this. Twice:
** After Aladdin tricks him into granting a free wish by getting him and Abu out of the cave.
** The second time (shown in the page picture above), after Princess Jasmine starts [[WeNeedADistraction pretending she's in love with Jafar,]] interrupting Genie's attempt to explain to Jafar that he can't make people fall in love. Jafar closes his mouth like a window-shade.
** He also does it briefly (complete with eyes bulging out) during his song "Friend Like Me", but it is just a part of his act. It's even literally in the lyrics.
-->'''Genie:''' (''singing'') So doncha sit there slack jawed, buggy eyed...
* Sebastian is the jaw-dropper in ''Disney/TheLittleMermaid'', when he sees Ariel with Eric during the reprise of "Part of Your World". Scuttle does the jaw-closing honors.

* Parodied in ''WesternAnimation/CorpseBride'', in the final scene, when it's revealed who killed the Bride, one of the members of the wedding's audience drops his jaw. ''Literally''. The jawbone falls to the floor in shock. Justified, as he's a skeleton.

* Happens to a boy in the dentist's waiting room (he is reading an ''[[WesternAnimation/TheIncredibles Incredibles]]'' [[EarlyBirdCameo comic]]) near the end of ''WesternAnimation/FindingNemo'', when he see the brief scuffle between Nigel the pelican and P. Sherman the dentist through the fish tank's glass (it's located inside a large rectangular hole in the wall separating the dentist's office from the waiting room). But that's not what solicits this reaction. He doesn't see Nigel; he only sees the dentist moving around like a maniac, while hearing the dentist's drill and Darla's screaming in the background. So, he has the Jaw Drop upon seeing that Sherman is apparently a DepravedDentist.
* Both Kaneda and Colonel Shikishima get one while watching Tetsuo's transformation during the climax of ''Manga/{{Akira}}''. It's probably the most realistic and justified jaw drop in Anime history.

* In ''Disney/TheLionKingOneAndAHalf'', Pumbaa gets a rather impressive one when Timon, scrounging for ideas on how to stall the hyenas until their trap is ready, ''proposes'' to Shenzi.
* Played with in ''WesternAnimation/{{Cars}}'' when the Chick Hicks pit crew drop their bumpers upon watching Guido change tires ''like a boss''.

* In ''WesternAnimation/TheBookOfLife'', Xibalba does an epic one after [[spoiler:Manolo passes his challenge by taming the giant bull.]]

* In ''Disney/WreckItRalph'', Pac-Man does one after Ralph smashes the cake.
* In ''Disney/CinderellaIIDreamsComeTrue'', Jaq and Gus do it when they witness Anastasia flirting with the baker and actually ''being nice''.
* In ''Disney/TheHunchbackofNotreDameII'': A ''literal'' one from the Gargoyles at the end. [[spoiler: When ''Madeline'' tells them she'll take good care of Quasi and winks at them, making her the first person other than Quasi to notice that they are sentiment, causing them extreme shock and their mouths fall off]].
* In ''WesternAnimation/ToyStory2'', the main toys do a collective drop while they look at a group of Barbie dolls having a beach party in Al's Toy Barn.
* In ''WesternAnimation/{{Coco}}'', a skeleton guard's jaw drops (literally!) when he sees that Miguel, a mortal, has made his way into the Land of the Dead.
** Later, when Miguel tells Héctor that Ernesto [[spoiler:apparently]] is his great-great-grandfather, Héctor's jaw drops so far that his eyes fall into his mouth.
** Played straight in the climax: [[spoiler:Tias Rosita and Victoria react with shock at the woman behind the Riveras' ban on music singing for an audience at the Sunrise Spectacular.]]


[[folder:Films -- Live-Action]]

* In ''Film/ReturnOfTheJedi'', Nien Nunb does this when he sees that they are about to hit a low ceiling. They just barely manage to tip the surface.
* Both versions of ''Film/TheProducers'' feature an '''entire audience''' doing this during ''Springtime for Hilter'''s opening number.

* Combined with DramaticDrop in ''Film/Terminator2JudgmentDay''. Dr Silberman pulls the cap off a hyperdermic needle with his teeth (because Sarah Connor has broken his arm) so he can sedate her. When he sees the T-1000 walk through a barred door, the cap drops out of his mouth.
* ''Film/ManOfSteel''. Colonel Hardy does a faint but noticeable version when Faora-Ul steps out her spacecraft in a CustomUniformOfSexy.
* More noticeable in ''Film/{{Watchmen}}'' when Night Owl II watches Silk Spectre descend the stairs in her {{Stripperiffic}} outfit.

* Throughout the ''Literature/AuntDimity'' series, Lori is very apt to do this when given unexpected or astonishing information. Humourously related to her inability to conceal her feelings.

-->"Only [[EatingTheEyeCandy your jaw and mine]]."
* In the original ''Literature/TheMysteriousBenedictSociety'' book, the BigBad Mr. Curtain's jaw drops after, when having failed to open his secret door with the code-word "control," Reynie (correctly) suggests trying it in Dutch instead (you just add an "e" at the end.)

[[folder:Live-Action TV]]
* Happened near the end of the season 4 episode of ''Series/{{Blackadder}}'', "Corporal Punishment", when [[spoiler:Blackadder returned to the dugout when George and Baldrick thought he was dead, whereupon Blackadder took the opportunity to make use of his trademark snarkery: "Still the striking resemblance to guppy fish at feeding time."]]
* Early on in Mike's tenure as host of ''Series/MysteryScienceTheater3000'', he decides to call down to Deep 13 on his own initiative to complain about the movie (''Beginning of the End''). When Mike and The Bots learn what the Mads get up to when they think no-one is looking, it is so horrifying that Crow's jaw drops and Mike has to close it up for him.
* ''Series/StarTrekVoyager''. Captain Janeway has this reaction when Q says he wants her to be the mother of his child. It's not quite visible as he's got her bent over in a ''Film/GoneWithTheWind'' pose. In another episode Neelix is communicating with an alien race that speaks partially through body language. He adopts a number of postures while speaking to their consul, ending with him tilting his head and standing with his mouth open.

* ''Series/BuffyTheVampireSlayer''. In "A New Man", Giles holds a feather duster in his mouth while searching through a TomeOfEldritchLore. It falls out during a subsequent OhCrap exclamation.
* ''Series/TheJoeSchmoShow'' - the second season, ''Last Chance for Love'', or ''Joe Schmo 2''. Eleanor, the weeper, gets out her "coupon book of love" at the suggestion of Austin, the bachelor that she and the other girls on the show are supposedly pursuing.[[note]]''The Joe Schmo Show'' being a parody of reality shows in which most of the cast are actually actors performing to a script except for the chosen schmoes.[[/note]] She finds that one of the coupons, for a ten-minute foot massage, is missing. Cammy, the airhead, says that she had already used it with Austin, that she "thought it was okay," at which point the mouth of that season's Joe Schmo, Tim, forms a perfect jaw-dropping oval at what's going on around him.

[[folder:Pro Wrestling]]

* On GLOW, during Ashley Cartier's "Asking Ashley" segments, there would always be a letter from a guy named Tim.

Ashley's jaw would drop as she continued reading silently, ending with her tearing up the letter and chastising Tim for his lewd thoughts.
* When Wrestling/MikeAdamle was named GM of Raw, Wrestling/JohnCena and Wrestling/{{Batista}} could produce nothing but genuine expressions of [[http://www.wrestlecrap.com/induction%20files/adamle/adamlenewgm.jpg complete confusion]].
* When the backstage segment supposedly showing the Wrestling/BigBossMan reuniting Wrestling/AlSnow with his precious dog Pepper as promised instead concluded in [[ExactWords yet another]] [[IAteWhat example]] of Boss Man being the {{Kayfabe}} worst person ever, the Smackdown cameras cut to Wrestling/JerryLawler[[note]]who was usually obnoxiously pro-heel at the time[[/note]] looking hilariously gobsmacked at the announce table.

[[folder:Video Games]]
* ''VideoGame/SuperSmashBros Brawl''
** Wario humorously does this after [[spoiler:seeing King Dedede being assisted by Luigi and Ness, both of whom Wario had previously turned into trophies]].
** He also does it briefly for a taunt.
** King Dedede also gets one when Kirby suddenly appears on the trophy carrier he's driving. Given their [[FriendlyEnemy relationship]], this one borders on OhCrap.
* Dedede hilariously does it again in ''VideoGame/KirbysReturnToDreamLand'' when the BigBad [[TheReveal shows his true colors.]]
* ''VideoGame/TheLegendOfZeldaTwilightPrincess''
** Link's jaw drops when he sees Armogohma's [[spoiler:wimpy second form.]]
** Also when he sees [[spoiler:Midna's sexalicious [[SheCleansUpNicely true form]]. Lampshaded by Midna; she makes fun of him for being stunned speechless]].
** Speaking of Midna, she gets an at least somewhat serious one when she discovers that Zant has broken the Twilight Mirror.
** Actually, Link does that about every time he sees a Princess or somebody turning into one. Except the 2D games, where he has no visible mouth, duh.
** In ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', Link's jaw drops when he sees the combined form of Twinrova.
** Link [[OhCrap does this]] when [[spoiler: Groose skydives into Faron Woods, and crashes into Link]] in ''VideoGame/TheLegendOfZeldaSkywardSword''.
* The EvilChancellor in ''VideoGame/ChronoTrigger''.
* ''VideoGame/DonkeyKongCountry2DiddysKongQuest'': Diddy and Dixie do this before every boss fight. Considering that ''Donkey Kong Country 2'' was made by Rare which also did ''VideoGame/{{Battletoads}}'', this is not surprising.
* This is comically exaggerated when the final boss of ''VideoGame/{{Rayman}} 3'' goes OneWingedAngel. Rayman's jaw literally hits the ground. Not entirely surprising, considering [[AttackOfTheFiftyFootWhatever how freaking huge]] the boss is.
* In ''VideoGame/SuperGemFighter'', this befalls on anyone who gets hit with [[StreetFighter Akuma or Dan Hibiki's]] special throw command, which is either Akuma giving a speech or Dan's [[DreadfulMusician horrid singing]]. As the context of the game is ''comedy'', it's always a good kick to see the usually ComicallySerious Akuma get hit with it.
* In ''VideoGame/{{Battletoads}}'', the Toads do a combination of this and {{Eye Pop}}ping when a boss makes his/her entrance. This carried on into the CrossOver game ''Battletoads & VideoGame/DoubleDragon'', with the Lee brothers doing the same thing.
* ''VideoGame/{{Catherine}}''
** Vincent does an impressive one when he first wakes up and [[BedmateReveal sees Catherine in his bed]].
** In the [[spoiler:Bad Cheater]] ending, Vincent runs out of the Stray Sheep [[spoiler:hallucinating that Catherine is just waiting for him outside after rejecting his marriage proposal to her]], and promptly gets run over by a car. Orlando pulls a wonderful JawDrop at the sound of his friend getting squashed.
-->'''Orlando:''' [[OhCrap Oh fuck.]]
** Happens again in [[spoiler: both Freedom Endings (seeing as the True one is the same as the Good one but with an additional scene after the credits)]] when Jonny confesses to [[spoiler:having asked Katherine out]]. Both Vince and Orlando pull a magnificent, in-tandem dual JawDrop.
** One of the stills during the credits of the [[spoiler:Freedom True]] ending also shows Boss completely astonished (and with a proper JawDrop) at the fact that [[spoiler:Feather won her wrestling match]].
* Nihlus in ''VideoGame/{{Mass Effect|1}}'' gets a very bizarre equivalent when he first sees [[EldritchAbomination Sovereign]]. His side mouth mandibles twitch in an utterly alien gesture, which, however, leaves very little room to interpretation.
* In ''VideoGame/HolyUmbrella'', when the protagonist is surprised, his jaw drops as his face bulges out of the normal bounds of the CharacterPortrait.

[[folder:Puppet Shows]]
* In ''Film/MuppetTreasureIsland'', this is Captain Smollet and Mr. Arrow's response to "Big Fat Ugly Bug Faced [[EatsBabies Baby Eating]] O'Brien", a man so ugly he looks like an ''[[DudeLooksLikeALady attractive woman]]''.

* Agatha in ''Webcomic/GirlGenius'' does it [[http://www.girlgeniusonline.com/comic.php?date=20070427 here]] upon first seeing [[spoiler:the fake Heterodyne]], and Zeetha closes it with the comment that she should face the "new era" with some dignity.
** [[http://www.girlgeniusonline.com/comic.php?date=20111024 One of the Mechanicsburg councilors reacts this way]] to [[spoiler:Gil]]'s rampage.

'''Gabe:''' Shut up and [[EyePop help me find my goddammed eyes]].
* Jin of ''Webcomic/WapsiSquare'' looks like [[http://wapsisquare.com/comic/where-do-i-start/ this]] after encountering her mother alive and well.
* Occurs in some strips of ''Webcomic/BobTheAngryFlower''.
* ''Webcomic/YetAnotherFantasyGamerComic'':
** Beholders have a pretty large jaw, so when Bob lets his drop, [[http://yafgc.net/comic/0349-say-what/ it's impressive]].
** Lewie the Lich, being mostly a [[DemBones skeleton]], can literally [[http://yafgc.net/comic/0635-behold/ drop his jaw to the floor]].
* ''Webcomic/MagickChicks'': This winds up happening a few times:
** Just about everyone present was [[StunnedSilence stunned speechless]] when Melissa [[http://www.magickchicks.com/strips-mc/the_dud laid Rain out in seconds flat]], [[BeatThemAtTheirOwnGame without having to cast a single spell.]]
** About a week later, [[spoiler:[[ADarkerMe Dark]]]] Skye stunned Callista at her own birthday party, [[http://www.magickchicks.com/strips-mc/source_of_entertainment by frenching her girlfriend right in front of her]]. Then left everyone slackjawed [[http://www.magickchicks.com/strips-mc/see_you_monday when she departed on a wolfback.]]
* [[ActionGirl Haley's]] jaw drops in ''Webcomic/TheOrderOfTheStick'' strip [[http://www.giantitp.com/comics/oots0250.html "Oh no, he DIDN'T!"]], when [[OnlySaneMan Roy]] finally snaps and tells KnightTemplar Miko to shove it. Then Haley hugs him.
* In ''WebComic/TheAdventuresOfDrMcNinja'', the death of [[spoiler: King Radical]] in the final chapter causes some dropped jaws, especially Gordito's. His in particular is probably due to not just the dramatic event but the CrazyAwesome way in which it is achieved: [[spoiler: Dr. [=McNinja=] sneaks behind {{Dracula}}, grabs him by the ankles and swings him mouth first at King Radical, making him accidentally bite him into a vampire. Then he grabs the pope and throws him at King Radical, [[HolyBurnsEvil making him explode]].]]

[[folder:Web Original]]
* This happens a lot to WebVideo/TheNostalgiaCritic.
** He jaw-drops during his ''[[Film/TheNeverendingStory Neverending Story 3]]'' review, when the the Rockbiter starts singing ''Born to be Wild''. About a 1 feet drop. It's a simple special effect, but quite effective.
** From the ''WesternAnimation/{{Captain Planet|and the Planeteers}}'' review:
-->'''Critic:''' So, Captain Planet. What other issues are you going to talk to grade-school kids about?\\
'''Todd Andrews:''' AIDS?\\
''(drum beat as the Critic's jaw drops)''
** And in ''Return of the Nostalgic Commercials'':
-->'''Critic:''' I mean, can you think of any other commercial that can be taken the wrong way so easily?\\
'''Man in the next commercial:''' Just wait'll you see what I've got. ''(fishes out a box)'' It's the Wunder Boner!\\
''(dramatic sting as the Critic's jaw drops)''
** During his review on ''WesternAnimation/TomAndJerryTheMovie'', this is his reaction to the silent duo suddenly [[SuddenlyVoiced singing]] about how they are now best friends.
* When Creator/BradJones reviewed ''[[Franchise/WinnieThePooh Too Smart for Strangers]]'' on ''WebVideo/DVDRHell'', his jaw dropped when Pooh started singing a song about kids getting molested. He was joined in by his wife, [[AnimalReactionShot his cat Lloyd]], and ROB the robot. In an interview, Brad said that this was his reaction in real life. He paused the DVD and called Jillian in to watch the rest of it.
* A decidedly non-comedic version with the Internet meme [[http://knowyourmeme.com/memes/omg-cat OMG Cat]], featuring a cat whose jawbone had been dislocated. The image resulted from her owner putting out an urgent call for help to [[ImageBoard 2chan]], asking them what to do since this happened at night, when the animal hospital was closed.
* LetsPlay/{{Markiplier}}'s jaw dropped when he played the sixth night of ''VideoGame/FiveNightsAtFreddys2'' and learned the big deal PlotTwist:
-->[[spoiler: "It ''is'' a prequel!]]
** He got one in earlier in the fourth night of the [[VideoGame/FiveNightsAtFreddys first game]] as he realizes what's [[KilledOffForReal going to happen to Phone Guy.]] [[spoiler: Then Foxy gets him.]]

[[folder:Western Animation]]
* Creator/TexAvery favored them in his [[WesternAnimation/TexAveryMGMCartoons MGM work]]. See the Droopy cartoons, for example.
* A surprisingly dramatic version happens when Jacob Marley visits Scrooge in Creator/RichardWilliams's version of ''Literature/AChristmasCarol''. His jaw is literally unhinged from his skull, and has a cloth to keep it shut.
* ''WesternAnimation/{{Animaniacs}}'' uses this a lot, too. In the episode "Meet Minerva", this is a squirrel's reaction to seeing the title character clad in nothing but a towel.
** At one point in the ''WesternAnimation/PinkyAndTheBrain'' short "The Brain's Apprentice," not only does Pinky's jaw drop, but also his nose and his ''eyes''.
* ''WesternAnimation/{{Arthur}}'':
** Arthur and Buster each decide that their group of friends prefers the other character, and so essentially switch personalities in an attempt to seem more likeable. When the two each enter [[LocalHangout The Sugar Bowl]] behaving exactly as the other would, all of their friends are completely [[MindScrew mind-screwed]] and [[OnlyKnownByTheirNickName the Brain's]] mouth falls open in shock. Francine closes it for him.
** In the episode "Arthur's Substitute Teacher Trouble," when the class finds out that their substitute teacher will be Mr. Ratburn's sister, ''Miss.'' Ratburn, Buster's jaw drops. He closes it back up only for it to drop again.
** In "Arthur's First Sleepover," Buster does highly exaggerated, cartoony versions of both this and an EyePop in his nightmare in which he discovers that Arthur and Buster are aliens, only to wake up, comment "That was scary," and flop back over to sleep.
* ''WesternAnimation/AvatarTheLastAirbender'':
** Zuko has this reaction when he walks into Sokka's tent (after bumping into Suki), and finds him ReadyForLovemaking.
** Sokka himself has had a number of these moments throughout the series, one of the most memorable being his reaction in "The Headband" to Aang enrolling in a Fire Nation school.
** In the SequelSeries ''WesternAnimation/TheLegendOfKorra'', episode "A Breath of Fresh Air", everyone present is completely shocked by the fact that [[spoiler:Bumi can now airbend, despite not previously being an airbender]]. Bolin, Meelo and Ikki's faces are especially hilarious.
* ''WesternAnimation/{{Cellbound}}'': The protagonist, a prisoner trying to escape jail inside a TV, is joyously pondering all the wonderful places in the world he's going to visit... then he slowly realizes that the TV has been delivered into the jail warden's office. Cue him baring his fangs and doing one heck of a jaw drop.
* Parodied in ''WesternAnimation/{{Chowder}}'', when Mung, Chowder and Gorgonzola wouldn't stop dropping their jaws several times to the floor.
* An episode of ''WesternAnimation/TheCritic'' features a costume party with the main character's father dressed as Film/TheMask. After he sees a woman, his jaw drops. Jay tells him to control himself until he sees the dessert cart and his jaw drops.
* Porkchop from ''WesternAnimation/{{Doug}}'' does one of these when he found out that Stinky the cat is a [[YourTomcatIsPregnant girl]] and had kittens.
* Parodied in ''WesternAnimation/FamilyGuy''. In order for the others to believe that Peter's new friend is actually Jesus, he [[BreastExpansion increases Lois' bust size several sizes]] and Brian's jaw literally drops to the table. [[note]]Hilariously, with a loud THUD.[[/note]]
** One episode started with the Griffin family watching an episode of ''Series/EightIsEnough'' which shows the father slapping his daughter eight times and another one of the daughters stops him and tells them that "eight is enough" and they all laugh. Cut to the whole family (except Stewie, who has a big smile on his face)looking at the TV with their jaws dropped.
* In the ''WesternAnimation/FantasticFourWorldsGreatestHeroes'' episode "[[Recap/FantasticFourWorldsGreatestHeroesZonedOut Zoned Out]]", [[RubberMan Reed]] does a rather impressive one upon seeing the large crowd of Negative Zone bugs after Ben's energy pack.
* In the ''WesternAnimation/HouseOfMouse'' short "Rollercoaster Painters", Mickey and Donald do this when [[DarkHorseVictory Goofy wins the lifetime pass]].
* In the ''WesternAnimation/JohnnyBravo'' episode "Johnny Meets Farrah Fawcett", Johnny's jaw drops progressively lower and lower as he watches Farrah Fawcett leave her car, and finally drops all the way to the ground as she's completely revealed.
* ''WesternAnimation/JusticeLeague''
** A subtle joke in the episode "In Darkest Night": Green Lantern is accused of destroying a planet and killing its three billion inhabitants. (To be fair, it was an accident. [[spoiler:And a hoax.]]) At the trial, a video is shown of Green Lantern's ring blowing the planet to smithereens. Superman, The Flash, and J'onn Jonnz all drop their jaws in horror. Hawkgirl, however, is [[ProudWarriorRaceGirl not fazed in the slightest]].
** And it happens again when the League [[spoiler:proves that the planet was never destroyed and the entire court is agape at being played for fools.]]
* ''WesternAnimation/{{Kaeloo}}'': Kaeloo usually does this when she is surprised or shocked (for example, after seeing Stumpy eat at a really fast speed and then dump all his food packaging on the ground).
* Kick does this in an episode of ''WesternAnimation/KickButtowski'' when he finds out Wade's been promoted and is never coming back to his favorite shop.
* Ron does this in the ''WesternAnimation/KimPossible'' episode "Emotion Sickness" on seeing Kim wearing a sexy black dress. Kim's dad even closes his jaw for him.
* A large number of ''WesternAnimation/LooneyTunes'' shorts feature these.
* In one episode of ''WesternAnimation/MightyMouse: The New Adventures'', one character's jaw drops all the way down from a helicopter.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic''
** Twilight Sparkle, Applejack, and Pinkie Pie go for the jawdrop when Rainbow Dash does the Sonic Rainboom in the episode of the same name. Fluttershy, amusingly enough, goes for a different kind of reaction, made funnier by her [[FlatJoy earlier attempts at cheering on Rainbow Dash]].
** Princess Celestia, of all ponies, gets in on this in the first episode of the second season, after [[spoiler:finding out Discord has already stolen the Elements of Harmony.]]
*** Cue a similar reaction from the Mane Six...except [[{{Cloudcuckoolander}} Pinkie Pie]] of course.
** Twilight after seeing the normally reserved Fluttershy seemingly take down a bear by kicking its back and snapping its neck; likely making viewers gave the same reaction as well.
** Pinky Pie, after seeing ExtremeDoorMat Fluttershy stand up for herself in ''Putting Your Hoof Down''. Rarity does the jaw-closing honors.
* In ''WesternAnimation/MyLittlePonyEquestriaGirls'', Twilight Sparkle and Spike both have this reaction when Human![[CrazyAwesome Pinkie Pie]] accurately sums up the plot of the movie [[IJustKnew based on "a hunch"]]. Two jocks do this when Applejack casually picks up a table and walks off with it while they had to work together to lift one.
* ''WesternAnimation/TheSimpsons'':
** In TheMovie, Scratchy's jaw drops at the sight of a whole heap of rockets flying at him, which promptly fill his gaping mouth.
** A similar scenario occurs with Bart and [[{{Squick}} a rat]] during an episode wherein Skinner expels him.
** A reporter does this when Mr. Burns spits out a piece of a mutant fish that he contaminated.
** The episode "Marge and Homer turn a couple play" has Homer and Bart (as well, all the male audience) having this reaction when Tabitha (a showgirl), in the Springfield Stadium, strips down to lingerie and launches into one of her own songs with lascivious dancing.
* ''WesternAnimation/StarWarsRebels'': [[StateSec Agent Kallus]] has done this a few times.
** [[Recap/StarWarsRebelsSparkOfRebellion "Spark of Rebellion"]]: His reaction to seeing Kanan [[CoverBlowingSuperpower get out]] his [[LaserBlade lightsaber]] on Kessel, complete with StunnedSilence.
** [[Recap/StarWarsRebelsS2E05WingsOfTheMaster "Wings of the Master"]]: When he sees the [[SuperPrototype B-Wing]] blow away the cruiser to his right with just a few shots from its WaveMotionGun.
--->[[ThisCannotBe "That's impossible!"]]
** [[Recap/StarWarsRebelsS2E15TheHonorableOnes "The Honourable Ones"]]: Kallus does it again when Zeb throws his bo-rifle up to the surface, followed by a look of silent indignation when Zeb throws the meteorite and transponder up as well.
* The ''WesternAnimation/SuperMarioWorld'' episode "[[GrandFinale Mama Luigi]]" had Bowser/King Koopa drop his jaw after seeing all the furniture in his room is gone thanks to [[BigEater Baby Yoshi]].
* The episode "Betrothed" of ''WesternAnimation/TeenTitans'' has a particularly extreme example given by Robin, where his jaw drops off the screen, loops back around, and drops onto his head.
* In an episode of ''WesternAnimation/TimonAndPumbaa'', the two are looking for treasure. During a fight, Timon places a dividing line and states that whatever one finds on their side of the line, they can keep for themselves. Pumbaa promptly unearths a gold nugget, to which a shocked Timon's jaw drops to the ground.
* ''WesternAnimation/TinyToonAdventures'' uses this fairly often. In one episode, Montana Max is so shocked that his jaw goes right through the floor and lands on the floor of the basement below him. When his mouth closes again, his body gets pulled down to where his jaw was sitting.
* Done a lot on ''WesternAnimation/TomAndJerry'', for instance in the short ''WesternAnimation/QuietPlease!'' when Tom reveals to Jerry that he's given Spike the bulldog "knock-out drops", foiling Jerry's plan to get Tom in trouble by waking the dog up. Also in "Mouse Cleaning", in when Tom does a wild double take as he sees a mess Jerry causes him to make.
* ''WesternAnimation/TransformersAnimated'' does this twice to Bulkhead. First time was in the premiere episode "Transform and Roll Out", where Prowl pushes Bulkhead's jaw up after Optimus pulls a few stunts they didn't know. The second time was in "Along Came a Spider"; Blackarachnia strokes Bulkhead's jaw while flirting, and it literally falls partially ''off''.
* ''WesternAnimation/{{Wakfu}}''
** Sadlygrove at the sight of his master, [[spoiler:Goultard]], vanquishing Rubilax in one blow.
** [[http://static.tvtropes.org/pmwiki/pub/images/Wakfu_Facepalm_9735.jpg Amalia]], when Grovy gets himself into a duel by defying her brother Armand. Followed by Eva doing a [[UpToEleven double]] FacePalm.
** Ruel, when learning that [[spoiler:Sadlygrove had seen Evangelyne naked, and not in a dream]].
* Raimundo from ''WesternAnimation/XiaolinShowdown'' when he sees a group of green monkeys jumping through the air to attack him. His jaw literally hits the floor.

[[folder:Real Life]]
* In the team finals of the 2012 UsefulNotes/OlympicGames, American gymnast [=McKayla=] Maroney, the reigning world champion on the event, hit a vault so astronomically spectacular that it has simply been known forever after as "[=McKayla=]'s perfect vault". But the audiences weren't the only ones impressed -- one of the ''judges'' [[http://www.buzzfeed.com/jpmoore/us-gymnast-mckayla-maroney-landed-the-vault-of-her actually did this at what she had just seen]].
* When O.J Simpson was acquitted, Rob Kardashian looked up at him with his mouth wide open.
* This reflex has actually been proven to have a [[https://achievement.ku.edu/relaxation-tips calming effect on the mind]]. Since your jaw naturally clenches when stressed or angry, letting it drop can release dopamine, thus calming you down.
