[[caption-width-right:350: From left to right: Alan (and some baby they found), Phil, and Stu.]]

->'''Alan''': When we get together, bad things happen and people get hurt.
->'''Chow''': Yeah, [[LampshadeHanging that's the point]]: [[HilarityEnsues it's funny]].
-->--''The Hangover III'', summarizing the entire series.

'''''The Hangover''''' (2009) is a comedy film directed by Todd Phillips (the maker of ''Old School'' and ''Film/StarskyAndHutch''). Four guys drive to Las Vegas for a bachelor party, and the bulk of the film deals with three of the friends ([[Series/TheDailyShow Ed Helms]], Creator/BradleyCooper, and Zack Galifinakis) trying to remember the events of the previous night while trying to track down the fourth - the groom - using clues they have on their person. HilarityEnsues.

The film won the Golden Globe Award for Best Picture (Musical or Comedy), making it the first live-action "pure" comedy -- one that was not a musical or a comedy/drama -- to win the award since 1993's ''Film/MrsDoubtfire''.

In 2011 ''The Hangover: Part II'' was released; it follows the three members of "The Wolfpack" from the first film as they wake up from another crazy night - this time, in UsefulNotes/{{Bangkok}}. The status of this film was in doubt due to a FrivolousLawsuit over the use of Mike Tyson's tattoo by Helms, but Creator/WarnerBros successfully got the lawsuit dismissed, and the film opened as scheduled.

''The Hangover: Part III'' was released in 2013, in time for Memorial Day. The Wolfpack [[BookEnds make their way back to Vegas]], this time they're not just cleaning up their own mess, but trying to survive an angry rival of Chow's who wants them to find his enemy - or else. The writers promise that it will be [[GrandFinale the end of the Hangover Trilogy]].
----
!!These films provide examples of:

[[foldercontrol]]

[[folder: The entire series]]
* DistressedDude: [[SubvertedTrope Subverted]] with Doug and Teddy in the first two films - [[spoiler:the only danger they're in comes from it taking two days to find them in the isolated locations they're trapped in and not of any direct threats on their lives]].
** Played straight in the third film, as [[spoiler:Doug is kidnapped and held hostage as incentive for the Wolfpack to track Chow down after he stole millions from Marshall]].
* FourManBand:
** OnlySaneMan: Doug
** TheSmartGuy: Phil
** The Pervert: Alan
** ButtMonkey: Stu
*** And then it becomes a ComicTrio: Phil leads, Stu complains, and Alan (the one that caused the mayhem in the first place) goes along with it.
* FourTemperamentEnsemble: Alan is Sanguine, Phil is Choleric, Stu is Melancholic and Doug is Phlegmatic.
* FreudianTrio: Alan (id), Phil (ego) and Stu (superego).
* GoodCannotComprehendEvil: When Stu tries to give Melissa a dressing-down, all he can come up is "you're... a bad person!".
* GoshDangItToHeck: Alan. So much. While pretty much every character in the series is not afraid of dropping a few f-bombs, Alan absolutely refuses. There are examples from all three films, but this exchange from the first movie sums it up quite nicely.
--> '''Phil''': GOD DAMN IT!
--> '''Alan''': Gosh darn it!
--> '''Phil''': SHIT!
--> '''Alan''': Shoot!
* HowWeGotHere: Part of each film shows the Wolfpack in various situations, and then they slowly retrace their steps. The third film subverts it, because they didn't get wasted like in the first two films [[spoiler:until the very end of the film at least]], but events that happened in the first film end up becoming important points in the third one.
* InsistentTerminology:
** Stu repeatedly calling himself a doctor in the first film, only for both Phil and the doctor who examined Phil to correct him by pointing out he's "really only a dentist."
*** Inverted in ''Part II'', after Phil gets shot in the arm - Phil asks Stu to check his wound because he's a doctor, and Stu insists he's just a dentist to try & get out of it.
*** Subverted in ''Part III'' when Phil attempts to motivate Stu by telling him "[[PunctuatedForEmphasis You. Are. A. Doctor]]". [[spoiler: It works.]]
* InterchangeableAsianCultures: Chinese Mr. Chow is played by Korean Ken Jeong, and Thai siblings Teddy and Lauren are Chinese and Korean respectively (and don't look remotely Thai).
* LargeHam: Alan, along with Stu and Leslie Chow.
* LivingProp: Stephanie, Phil's wife, has one line in each film and is never named on screen. This applies even more so in ''Part II'' where she spends her brief screentime hovering silently at Phil's shoulder, and her one line comes amidst several characters speaking at the same time [[spoiler:when Alan runs a speedboat aground and everyone is checking to make sure the guys are okay]].
* MadeOfIron: All of the Wolfpack appear to be this.
** In the first film Alan takes a stun gun to the face, a [[ImprovisedWeapon crowbar]] to the face, and a Mike Tyson punch [[RuleOfThree to the face]], all within one day. Phil is tased in the crotch, attacked by Chow with a crowbar, clawed by a tiger and on the side of the car that gets T-Boned. Finally, Stu is tased in the neck, hit in the crotch with a crowbar and rips out his own tooth
** In ''Part II'' all three guys are repeatedly beaten with a long stick of bamboo by a monk, and Phil gets ''shot in the friggin' arm'' but manages to get by fine with a few $6 stitches. Made of iron, indeed.
* NoodleIncident:
** Oh so subverted. At first it looks like the events of last night couldn't ever be anything but this, but by the end of the movie, the characters have a pretty good idea of what they did, and it lives up. Played straight, as they never get to know where they found the chicken (a popular theory is that they tried to feed it to the tiger) or how the chair ended up on fire.
** It's never been explained why Alan can't be within 200 feet of an elementary school or a Chuck E. Cheese, though this could be because he picks fights with children (see ManChild above). Zach Galifinakis says in the DVD commentary that Alan innocently tried to play with some children which of course looked suspicious to parents. It was all just a misunderstanding.
** "What are you talking about? I've found a baby before."
** In the second film, [[spoiler:the guys somehow managed to start a riot, which brought out the police and left part of Bangkok in ruins]].
* NotableOriginalMusic:
** "Stu's Song". Extra props for pronouncing "striped" as "stri-ped."
---> '' What do tigers dream of, when they take a little tiger snooze...?''
** ''Part II'' gives us "Alantown", a {{Parody}} of the BillyJoel song "Allentown", again sung by Stu.
* OhCrap: The first two movies are full of these moments, particularly right after the guys wake up.
* OnlySaneMan: Doug, and to a lesser extent, Phil. Stu would qualify if not for his tendency to completely flip out over (sometimes) minor things.
* OverprotectiveDad: Completely averted with Tracy's dad, who thinks it's okay for Doug to be late to the wedding if he's on a heater, and doesn't seem to mind the possibility of him getting herpes in Vegas and passing it onto his daughter.
* PhotoMontage: Happens during the credits of the first two films to show what happened during their respective nights.
* PowerWalk: Happens in all three films.
** In the first movie, when they are hitting the casino.
** In the second movie, when they are leaving the airport.
** In third third movie, [[spoiler: walking out to Alan's wedding.]]
* SerialEscalation: Every time it looks like they've got a handle on what they did, something even worse makes itself known.
* SignatureStyle: The Dan Band.
* TheSmurfettePrinciple: All three lead characters are male and most secondary characters with substantial screentime such as Doug, Mr. Chou and Teddy are male too. The first film has more of a female presence since Jade (Heather Graham's character) gets a fairly big supporting role but her counterpart in ''Part II'' appears in only one scene and the only other female characters with more than a couple of lines are Tracy and Lauren.
* WhatHappenedToTheMouse: In the sequels, Chow's two henchmen have not been seen since the first movie.
[[/folder]]

[[folder: Part I]]
* AbuseIsOkayWhenItIsFemaleOnMale: Subverted with Melissa, who is shrill and dominating over Stu, and has even beaten him twice over. When Stu actually calls her out on her unfair treatment, her reaction is along the lines of a "yeah, so what?" While it is PlayedForLaughs, she is acknowledged as unpleasant by the rest of the cast, and arguably the most pleasing aspect of the climax is Stu breaking up with her in a rather magnificent ([[BuffySpeak yet slightly befuddled]]) manner.
* AccidentalMarriage: Because you can't have a party in Vegas without somebody taking a spontaneous trip down the aisle.
* AlcoholInducedIdiocy: Obviously. [[spoiler:Except it's not from alcohol, it's from being unknowingly drugged.]]
* {{Animeland}}: When a naked, angry Asian man jumps out of the trunk of the car, Alan instantly tries to calm him down by saying that he hates Godzilla too.
** If you pay attention to Chow's face, it can become a CrowningMomentOfFunny: he leaves because he's just so ''confused'' by the Godzilla line.
* AnywhereButTheirLips: Among the first clues that Stu's girl really isn't right for him is that she won't let him kiss her on the lips.
* ApatheticTeacher: Phil pretty much doesn't give a rat's ass about the kids in his class.
* BlackComedy: "Hey Phil, look! [laughs heartily] He's jacking his little weenus!"
** Phil chuckles before turning away, and Stu actually ''laughs out loud'' before putting on an "offended" face and telling Alan to knock it off.
* TheCameo: Mike Tyson as himself. Also [[spoiler:Carrot Top and Wayne Newton during the end credits photo montage]].
* CatchPhrase: Phil says "No shit it's X" often enough during the course of the movie for it to count as one.
** Phil also says "No, this is good!" every time they remember something terrible from the night before. Stu eventually [[LampshadeHanging calls him on it]].
** Alan: "That's classic!"
** Stu: "WHAT THE FUCK IS GOING ON?!"
* ChekhovsBoomerang: [[spoiler:The mattress]]
* ChekhovsGun:
** Or his ring, in this case. As soon as the Holocaust ring is introduced, you know something is going to happen to it. [[spoiler:Stu uses it when he gets married to a hooker.]]
** Also, the [[spoiler: "This Door Locks Behind You" sign on the door to the roof was a pretty obvious sign that somebody was getting locked up there at some point - though by the time they found Doug, it had long been forgotten.]]. Possibly a BrickJoke.
* ChekhovsGunman: As the guys are waking up, a woman is leaving the room. It turns that she actually married Stu the night before.
* ChekhovsSkill: Card-counting.
* CluckingFunny: After the night in Vegas, there is a chicken wandering around the group's hotel room. It is never directly addressed or explained.
** Popular theory is that they tried to feed it to the tiger.
* ComicallyMissingThePoint: Stu is more concerned that [[InsistentTerminology his friends get it right who his girlfriend cheated on him with]] (a bartender, not a bellhop) than with the fact that she cheated on him in the first place.
* CoolCar: You'll never see a finer example of a 1969 Mercedes-Benz convertible on film. [[spoiler: Too bad they gradually smash the shit out of it as the movie goes on.]]
* CreatorCameo: Director Todd Phillips is the man they walk in on [[IncrediblyLamePun going down on his girlfriend in the elevator]].
* DangerTakesABackSeat: In the form of [[spoiler:a tiger]], although they put it in there.
* TheDitz: Jade plays this during Alan's [[spoiler:second]] blackjack haul.
* DudeNotFunny: [[InvokedTrope Invoked]] with Mike Tyson's reaction to Phil dry humping his tiger.
* EurekaMoment: How Stu figures out where Doug is.
* FanDisservice:
** Alan's naked ass. When we thought it couldn't get any worse than that, a wrinkled, overweight old man gets a physical exam in front of the heroes, and we're subjected to a shot of his backside as well.
*** Even worse - [[spoiler:his dick being sucked by an elderly woman in the credits.]]
** [[spoiler: Mr. Chow popping out of the trunk, totally naked, his already small penis obscured by a lion's-mane of pubic hair]].
* FanService:
** Phil waking up without a shirt on. Also when he wears that black suit.
** HeatherGraham whipping her tit out. Also all the naked women in the photos that play over the credits.
** The numerous shots of women in their bikinis at the pool.
* FinishHim: The male cop screams this while goading a kid to taser Alan.
* GenreSavvy: When the guys go to retrieve their car from the impound Stu says "Ten to one odds the car is beat to shit! Like fucked up beyond all recognition". [[spoiler:Ultimately averted when the car turns out to be in perfect condition, though this changes later on.]]
* GroinAttack: Phil gets zapped in the crotch during the tasering class.
* HaHaHaNo: "HAHAHAHA...[[PrecisionFStrike fuck you]]."
* [[HenpeckedHusband Henpecked Boyfriend]]: Stu. [[spoiler:He manages to break up.]]
* HeroAntagonist: The cops.
* {{Homage}}: To ''Film/RainMan'', when Alan gets their cash back.
--> '''Phil:''' Don't you have to be really smart to count cards?
--> '''Alan:''' Oh yeah? Someone should tell that to Rain Man. He nearly bankrupt Vegas and he was a [[ItsPronouncedTropay "ruh-TARD."]]
* HopeSpot: When the three amigos [[spoiler: win their $80,000 back and are celebrating that they'll now get Doug back. Then the trade happens.]]
* HowWeGotHere: Pretty much the whole movie, after Phil calls Doug's fiance.
* HypocriticalHumor: AmbiguouslyGay Mr. Chow referring to the heroes as "gayboys".
* [[ImADoctorNotAPlaceholder I'm a Doctor Not a Tour Guide]]: Spoken by the doctor that treated Phil.
* InsistentTerminology: Alan's bag - Phil call it a man-purse, and Alan insists it's a satchel. He later gets into an argument with Chow on the matter.
-->''It's not a purse, it's a satchel. IndianaJones wears one.''
** "It was a bartender!"
*** And he didn't even cum inside her!
* InstantWinCondition: Despite all the terrible, terrible consequences of all their activities in Vegas, when the main characters [[spoiler:find Doug and return him (mostly) on time to the wedding]], that's it, conflict over.
** Of course, they did [[spoiler:blackmail the cops into letting them go without jailtime or any records (but not without hilarious results), Mike Tyson forgives them for the tiger incident, Jade acknowledges the marriage as stupid and allows Stu to leave, and the Triads[=/=]Yakuza[=/=]''Whatever the Hell a Korean Mafia is Called'' only wanted the money.]]
** [[spoiler:They even ended up winning 80,000 dollars that Doug managed to hold on to.]]
** [[spoiler:That money probably went to cover the damage to the hotel room.]]
*** [[spoiler: And the car.]]
*** [[spoiler: And possibly an "I'm sorry" gift for Doug's new bride.]]
* {{Jerkass}}: Melissa and the cops who [[spoiler:get their cruiser stolen by the Wolfpack.]]
* JustKeepDriving: When they are taking [[spoiler: the tiger back to Mike Tyson's house]] and they hit the bus, then stop the car in the middle of the road. None of the other vehicles bother to stop.
* LyricalDissonance: Singing a rap song during a wedding? Fine. Maintaining its sexually explicit lyrics, f-word and all? [[CrowningMomentOfFunny Hilarious.]]
* NakedPeopleAreFunny: And '''''dangerous'''''.
* OneSteveLimit: An important plot point is that [[spoiler:there are two characters named Doug - a drug dealer who sold the roofies to Alan, and the lost groom. They wind up inadvertently rescuing the first Doug, who inspires a EurekaMoment, which leads to them finding Doug on the roof.]]
* OntologicalMystery: Three friends wake up in a Vegas hotel room with serious hangovers and no memory of what happened last night. One of their friends is missing and there are signs of them having been involved in some kind of wild party. From there the rest of the film is about the trio investigating to figure out just ''what the hell happened''.
* PlotArmor: Among other things, [[spoiler:how Doug survived spending 36 hours on the roof of a Vegas hotel without water and minimal shade.]]
* RedHerring: You'd really think that Alan's comment about not being allowed within 200 feet of schools or Chuck-E-Cheeses was going to come back to haunt them later in the movie.
** Stu's missing tooth might count. It seemed like it would be just as much of a clue as all the other weird stuff they found, but it turns out it doesn't have any relevance to finding Doug, [[spoiler:Stu just pulled it out himself for a dare]].
** Not mention when they hear the banging in the trunk.
* TheReasonYouSuckSpeech: Stu gives one of these to Melissa at the end of the film, much to Phil's delight.
* RunningGag: Two instances of InsistentTerminology.
** "He was a bartender!"
** "You're a Dentist, not a doctor."
* ShaggyDogStory: [[spoiler: Nearly the entire movie, considering where Doug really was.]]
** Subverted. Imagine how screwed up everything would have been if [[spoiler:they had found Doug instantly and just left]]. Jade, the Koreans, Tyson, the cops... ''everyone'' would have been after them.
* ShoutOut:
** [[spoiler:The wedding singer is the same one from Phillips' ''Old School'' and ''Film/StarskyAndHutch''.]]
** Also, ''Film/{{Gremlins}}'' is referenced in the dialogue.
** Alan obliquely refers to ''Three Men And A Baby'' when they meet up with Jade.
** The scene in the desert with the protagonists' car reflected in Mr Chow's sunglasses is a direct reference to ''Casino'' ([[CaptainObvious also set in Vegas]]).
** Three men sitting in a car, then hearing a thumping sound from a person in the trunk might also invoke memories of ''{{Goodfellas}}'', another Scorsese film.
** ''TommyBoy'': [[spoiler:The tiger waking up and destroying the CoolCar is a direct echo of this, especially the shot of the animal pausing to kick out the window.]]
** "What happened to [[TheWire Omar]]?" [[http://youtube.com/watch?v=ELc9Aw3fS-g "Don't worry about Omar, he's not with us no more."]]
** And the ''Film/RainMan'' tribute in the casino complete with the same actress in the casino scene in that movie wearing the same dress.
** One of the songs used in the soundtrack is KanyeWest's "Can't Tell Me Nothing", which Galifinakis created [[http://www.funnyordie.com/videos/451fba17e0/cant-tell-me-nothin-from-zach-galifianakis an alternate music video]] for in 2007.
* SincerestFormOfFlattery: By the end of the film, Alan's taken to mimicking Phil. [[spoiler:When Phil realises this, as they wait for Stu so they can leave, his expression looks like a non-verbal FlatWhat.]]
* TrailersAlwaysSpoil: The [=DVD=] commercial points out the [[spoiler:OneSteveLimit]].
* TrespassingToTalk: The trio come back to their hotel room to find Mike Tyson waiting for them and their explanation as to why they have his tiger.
* VivaLasVegas: Trope Exemplar, but also {{Deconstructed}} since it shows the consequences of a night out on the town.
* VomitIndiscretionShot: Three of them, although one's a still photo during the end credits and another is in black and white so only one is really {{Squick}}y.
* WasntThatFun: After Alan almost navigates them into a semi truck on the freeway while they're driving to Vegas.
-->'''Alan:''' "That was awesome!"
-->'''Doug:''' "That was NOT awesome, what is wrong with you?!"
* WatchThePaintJob: Since the Mercedes is ThePreciousPreciousCar, of course it'll be wrecked beyond recognition.
* WhatHappenedToTheMouse: Some viewers were preoccupied the entire movie with just the mystery of the chickens [[spoiler: (which is never really resolved)]], a very minor detail.
** We also never truly find out what landed Phil in the hospital.
*** In the credits, [[spoiler: he's slapped by the tiger.]]
** We never find out where the sword stuck into the couch came from either.
** In the theatrical edit, there's also the matter of the trashed Mercedes. [[spoiler:The Unrated version adds a scene just before Alan finds the camera, which reveals the car is a wedding gift to Doug and Tracy from Tracy's parents.]]
* WhatDidIDoLastNight: The main characters spend the whole movie trying to figure out the answer to this question. The answer? Everything you can do in Vegas, and then some.
* WhereItAllBegan: [[spoiler:The guys finally find Doug on the hotel roof, where the whole night started.]]
** In fact, they really had all the clues they needed within a few minutes of figuring out he was gone.
* XMeetsY: ''Film/VeryBadThings'' meets ''{{Superbad}}'' with a pinch of ''ThreeMenAndABaby''.
[[/folder]]

[[folder: Part II]]
* ArcWords: "Bangkok has him now" in relation to [[spoiler: Teddy.]]
-->"[[LampshadeHanging Why does everyone keep saying that?!]]"
* BackFromTheDead: [[spoiler: Mr. Chow.]]
* BlackComedy: [[SubvertedTrope Subverted]] with Phil and Stu's initial reaction being along the lines of DudeNotFunny to Alan using a plastic bottle to simulate an erection, but when [[spoiler:a monkey starts nibbling on it]], everybody bursts out laughing.
* ButtMonkey: ''Part II'' itself; it's attracted no less than four lawsuits, [[http://www.gossipcop.com/louis-vuitton-suing-hangover-2-knockoff-bag-luggage-lawsuit-alan-warner-bros/ with Louis Vuitton filing the fourth over a phony bag with his name on it.]]
* CallBack:
** Phil's phone call to Tracy to tell her they've lost Doug gets one .
--> '''Phil:''' It happened again.
--> '''Tracy:''' Seriously, what is wrong with you three?
** When the guys wake up and realize that they had another wild night, their initial reactions provide several call backs to the waking up in the first film, such as Stu asking about his teeth after Phil and Alan's shocked reactions to his new tattoo; and Alan immediately [[spoiler:being asked if he roofied them again]]; and once they realize Stu's future brother-in-law is missing, one of the first places they check for him is the roof.
** [[spoiler: Chow jumps out of an icebox and, once again, begins beating on the three guys in ''Part II''. Thankfully this time he is clothed.]]
* CountryMatters: Phil refers to Melissa as "a cunt", not that anyone can blame him.
** [[UnsettlingGenderReveal "This is Bangkok,]] [[IncrediblyLamePun not Bangcunt".]]
* DarkerAndEdgier: Bangkok makes for a grittier setting than Vegas. Not to mention the whole bit about the severed finger and [[spoiler:transvestite]] strippers.
* DatingWhatDaddyHates: Lauren's dad makes no secret of his distain for Stu.
* DisneyDeath: [[spoiler:Chow.]]
* DrivesLikeCrazy: Chow during the chase scene.
* EasilyForgiven: Alan in the second one. The Vegas incident can be attributed to his own ignorance rather than malice, but that excuse only works once. Not to mention they asked him if he drugged them the second time, and he not only straight-up ''lied'' to them, but swore to God.
* EurekaMoment: How Stu figures out where Teddy is.
* EverythingsBetterWithMonkeys: The second film has a monkey, with Alan's childishly gleeful reaction invoking this in the movie.
--> '''Alan:''' ''[With childlike glee in his voice]'' Ooooh, it's a monkey!
* FanDisservice: [[spoiler: All the "girls" at the club turn out to be ladyboys, and while they prominently display breasts, they also have the male package down there. Then Stu finds out what he did with one of them the night before.]]
* FilkSong: Stu turns BillyJoel's "Allentown" into "Alan Town" ("Well, we're living here in Alantown, and he's driven our lives into the ground...").
* {{Fingore}}: Teddy loses a finger [[spoiler:(all in good fun though, as he was playing five-finger fillet with a bowie knife and after severing the finger on a misaimed thrust the group plays with the detached digit)]].
* FullNameUltimatum: "Stuart Price! You get your ass back here right now!"
* FunnyBackgroundEvent: After Alan [[spoiler:runs the speedboat aground and it eventually comes to a stop to the side of the wedding, he can be seen dropping the anchor on dry land]].
* HolidayInCambodia: The general premise.
* HopeSpot: [[spoiler:Kingsley uses Teddy as insurance that the guys get Chow to complete their "business transaction". Then when the deal happens it turns out those guys don't actually have Ted, it was just a sting operation and Chow gets arrested.]]
* HowWeGotHere: Again, like in the first movie. Even has a CallBack.
* HypocriticalHumor: [[spoiler: Mike Tyson]] tells Stu that he should have his tattoo removed. As in, [[HilariousInHindsight the exact same tattoo that]] [[DontExplainTheJoke Tyson has on his face]]. [[invoked]]
* IDontLikeYouAndYouDontLikeMe: Stu's father-in-law-to-be says that he's never told Stu, but he doesn't like him. Stu sheepishly responds that he already knew that.
* JerkAss: Kingsley [[spoiler:although it's an act]] and Stu's father-in-law.
* KarmaHoudini: It turns out that, as opposed to the first film, [[spoiler: Alan ''deliberately'' roofied everyone, even if he was only targeting Teddie, which really doesn't make it any better.]] Other than the others getting mad with him for about a ''minute,'' there are no repercussions.
** And ''two'' counts for when [[spoiler: Stu slept with Kimmy, a kathoey (transgender woman) prostitute. One since, as Stu was clearly wasted and couldn't give informed consent, Kimmy ''raped'' him. Two since, even though Stu ''was'' wasted, the incident is quickly brushed over and he goes on to marry his fiancee without telling her the truth, or even ''getting tested for a quite possible STD''.]]
* OhCrap: [[spoiler:"Is that Alan driving the speedboat?"]]
* MajorInjuryUnderreaction: [[spoiler: Teddie is ridiculously calm about the fact that he not only ''cut off his own finger,'' but that the guys irretrievably lost it in Bangkok, with no chance of getting it reattached. The guy is a talented musician and is also ''training to be a surgeon''; this is quite possibly a career destroying injury. But nope; all he does is shrug. Wacky Bangkok.]]
* MaleFrontalNudity: Mr. Chow [[spoiler:and the transgender strippers.]]
* MexicanStandoff: Chow apparently always ends up in one of these. He met his wife at one.
* NotQuiteDead: [[spoiler:Chow.]]
* OnlyAFleshWound: Phil is shot in the arm. Only grazes him and leads to 8 stitches, but he makes sure to point out that had the bullet gone a little to the left, it would've killed him.
* ThePasswordIsAlwaysSwordfish: The password to Chow's overseas bank account is Baloney1.
-->'''Chow:''' Well, it used to be just baloney, but then they started making you add ''number''.
-->'''Kingsley:''' Fuckin' annoying...
* PlotArmor: [[spoiler: How Teddy survived in an elevator with no food or water and a cut off finger.]]
* RapeAsComedy: [[spoiler: Stu is raped by the transsexual hooker]].
* TheReasonYouSuckSpeech: Lauren's (Stu's fiancee) father gives a speech at the rehearsal dinner that essentially amounts to him insulting Stu and comparing him to dull, flavourless rice. [[spoiler:At the end of the film, Stu inverts this and gives a [[CrowningMomentOfAwesome "The Reason I Don't Suck" Speech]].]]
* [[RecycledINSPACE Recycled in Bangkok]]: It's pretty much the same movie, except in Bangkok, and with a different groom missing.
* {{Scandalgate}}: Mike Tyson's tattoo artist threatened to block the release of ''Part II'' after he claimed copyright over the facial tattoo Stu gets in the movie; this was dubbed "Tattoogate" by the media. Had this been released before the lawsuit was filed, Tyson himself recommending that Stu remove his tattoo at the end of the film would really be a FunnyAneurysmMoment.
* ShaggyDogStory: Played straighter in ''Part II'' than in ''Part I''- [[spoiler:Teddy was in the elevator on his way to get ice for his severed finger, when the power went out a minute after Phil and Alan woke up. If the trio had figured that out there and then before going back to the resort, they would've just needed to explain Stu's tattoo and get Teddy to a hospital, instead of getting dragged into Chow's dealings.]]
* SequelGoesForeign: ''The Hangover: Part II'' takes place in Thailand and includes the characters [[LampshadeHanging lampshading]] the fact that the same circumstances happened in a foreign country.
* SharpDressedMan: Alan as the guys are walking through the airport.
* ShipSinking: ''Part II'' kills off the Stu/Jade ship.
* ShoutOut:
** One of that's pretty much GeniusBonus: one of the pictures in the end credits montage is inspired by a famous [[UsefulNotes/TheVietnamWar Vietnam War]] [[http://en.wikipedia.org/wiki/File:Nguyen.jpg pic.]] [[http://www.badassdigest.com/2011/06/01/the-best-part-of-the-hangover-part-ii Some liked it]], but Creator/RogerEbert [[http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20110524/REVIEWS/110529989/1001/reviews was horrified]].

* SirSwearsALot: Kingsley [[spoiler:a.k.a. Detective Peters]].
* StrictlyFormula: ''Part II'' is pretty much the same exact thing. [[RecycledInSpace IN THAILAND]]!
* StylisticSuck: Mike Tyson's singing can only be described as this.
* TrailersAlwaysSpoil: TV ads that ran the week ''Part II'' was released featured heavily the "Time in a Bottle" elevator scene, [[spoiler:so when Chow dies 30 minutes in, you're pretty sure it's not going to stick.]]
* TheTysonZone: The TropeNamer asks to see the photos of the Wolf Pack's wild night by saying "I'm Mike Tyson. Nothing surprises me." And he still reacts to the pictures with a cry of "Motherfuck!"
* UnsettlingGenderReveal: [[spoiler:Stu and the transsexual prostitute]].
* TheVoiceless: The elderly man in the wheelchair. At first they're confused as to why he doesn't speak, and why he's wearing Teddy's hoodie [[note]] The hoodie was given to the monk by Teddy the previous night when they were rioting at a bar, prompting the police to fire teargas at them, so the elderly man wouldn't be subjected to it. Which also explains why he had all of Teddy's wallet contents on him, such as ID cards[[/note]], but then they learn he's a monk who has taken a vow of silence, and not even the other monks would be able to get him to speak.

* WhatDidIDoLastNight
* YouLookFamiliar: Bryan Callen played Eddie in the first film, and returned as the owner of the strip club featured in ''Part II''. Due to make up, the characters don't look the same, but ''sound'' the same.

* AffablyEvil: Marshall is vicious and murderous but it's so that he proves a point and not because he finds pleasure in it. When he sees that Alan wet himself after seeing Black Doug killed, he tells Alan not to be embarrassed and provides a pair of sweatpants.
* ArtifactTitle: ''The Hangover: Part III'' ditches the set-up of the first two films, and doesn't have the Wolfpack retracing a wild night they can't remember [[spoiler: until TheStinger]].
* BackForTheDead: [[spoiler:Black Doug.]]
* BedsheetLadder: Off the side of [[spoiler:Caesar's Palace]].
* BigFancyHouse: The Mexican villa. [[spoiler:Believed to belong to Chow in the past, but actually belongs to Marshall.]]
* BlackComedy: The third film is almost entirely a black comedy.
* BlackDudeDiesFirst: [[spoiler:Black Doug]] is shot and killed by [[spoiler:Marshall]].
* BondOneLiner: After [[spoiler:Marshall and his men shoot into the trunk where they believe Chow is holed up]]: "[[ItMakesSenseInContext End of conversation.]]"
* CallBack:
** Phil makes a joke about Stu getting tested for any disease from the face tattoo, though he is obviously making jokes about Stu's encounter with the hooker in Bangkok.
** Before the third film ends, there is a shot of the Wolfpack walking together [[spoiler:to Alan's wedding]] as they've done in the past.
* ChekhovsGunman: In the first movie, when Stu was explaining [[spoiler: to Black Doug that he gave Alan the roofies instead of ecstasy, he claimed someone named Marshall will get mad at him for it]]. Marshall shows up in Part III.
* CluckingFunny: Chows cock-fighting roosters that attack the Wolfpack, they are fed nothing but cocaine and chicken.
* ComicTrio: Phil leads, Stu complains, and Alan goes along with it [[SpannerInTheWorks when not making things worse]].
* CoversAlwaysLie: The movie poster that parodies the ''Harry Potter'' poster shows Las Vegas on fire. The city is fine in the movie.
* CreatorCameo: Todd Phillips is the guy paying the prostitute that Chow parachutes by.
* DarkerAndEdgier: ''Part III'' is this to ''Part II'' (which was this to the original). ''Part III'' includes [[spoiler:four onscreen human deaths (three of them murders)]], a plot involving Phil, Stu and Alan trying to drug Chow to deliver him to a gangster in return for Doug and a lot of animals dying in gruesome ways.
* GenreShift: See DarkerAndEdgier. Many critics were puzzled by how violent and action-oriented the movie is, to the point where some where wondering if it was even ''supposed to be a comedy''.
* GoThroughMe: [[spoiler:Alan does this for Phil when Chow had his gun pointed at the latter. Since Chow considers Alan a friend, partly because he's the only one who wrote to him while in jail, and more importantly, opened the trunk and gave him his gun, thus allowing him to survive Marshall's attack, Chow ultimately relents and allows them to live.]]
* GrandFinale: To hammer the point home, several of the movie posters just have "It Ends" for the tagline, except for the group poster, which has "The End", and the poster that homages ''Film/HarryPotter'', which has "It All Ends".
* HeadphonesEqualIsolation: ''Part III'' has a shot of Alan, smugly listening to music through some headphones, as [[spoiler:his father dies from a heart attack in the background]].
* TheHeist: Part of the plot this time around, the Wolfpack has to locate Leslie and steal back $21 million dollars worth of gold for another drug lord.
* ImpersonatingAnOfficer: As seen in a flashback, Chow doing this sets the plot of the film in motion.
%% Killed Off For Real only applies to settings where resurrection is possible. Find another Death Trope to use.
%%* KilledOffForReal: [[spoiler:Sid, Black Doug, Marshall, and his goon. And the poor giraffe.]]
* LowClearance: The giraffe being decapitated on the highway and its head flying into an unsuspecting family's minivan. WhatTheHellHero
* MeaningfulBackgroundEvent: [[spoiler:Sid's heart attack in ''Part III'', in the background of a shot focused on Alan listening to music through his headphones]].
* MeaningfulFuneral: Played for laughs with Alan's angelic performance of Ave Maria at his dad's funeral.
* OffWithHisHead: Alan hauls a giraffe onto a highway with his car. Then it [[LowClearance gets by an overpass]]...
* ThePasswordIsAlwaysSwordfish: Alan's changed his phone's password to "heyphil", to Phil's confusion.
* PlotTriggeringDeath: The third film starts with Alan going off his meds after his father passes away. His friends offer to take him to rehab, but the main story ambushes them en route.
* PrisonRiot: Chow starts one so the guards would be distracted as he escaped.
* RuleOfThree: Todd Phillips did this to finish the series out as a trilogy.
* ShoutOut: [[http://ewinsidemovies.files.wordpress.com/2013/03/hangover-3.jpg This poster]] spoofs [[http://images.wikia.com/harrypotter/images/d/df/Harry-potter-and-the-deathly-hallows-part-2-movie-poster-01.jpg the face-off]] between a certain EvilSorcerer and [[Film/HarryPotter his boy wizard nemesis]]...
** Chow's prison escape is [[TheShawshankRedemption pretty obvious]].
* SuddenSequelDeathSyndrome: This happens to [[spoiler:Alan's dad, Sid Garner]], courtesy of [[spoiler:Alan giving him a heart attack when he hauls a giraffe onto a highway with his car, only to have it graphically decapitated by an overpass, and especially because of Alan's nonchalant reaction to what his dad had to do in order to fix the mess]]. This also ends up sending the entire plot into motion.
* TakeThatCritics: TheStinger is one to everyone who complained how unbelievable it was that [[spoiler:the Wolfpack had a second wild night they couldn't remember in ''Part II'']].
* TheStinger: [[spoiler:The Wolfpack wakes up after yet another wild night they can't remember.]]
* VillainousRescue: Happens twice to the Wolfpack in this film:
** The first is when they're bailed out of a Mexican police station. [[spoiler:By Marshall, whose house they had just broken into.]]
** The second time, [[spoiler:they're rescued by Chow, whom Alan helped free and gave him access to his handgun. When Marshall finds out Chow wasn't in the trunk of the limo, he was prepared to shoot them, until Chow pops up from the limo top, and shoots him and his bodyguard in the head.]]
* WireDilemma: Stu and Chow have to cut the same wire on two panels of a security system at the same time to disable it, but Chow is colorblind and dyslexic.
* YouHaveOutlivedYourUsefulness: A couple of examples:
** [[spoiler:Chow does this to the Wolfpack when they help him steal the gold from the Mexican villa. He then proceeds to reactivate the alarm, and then snaps the necks of the sleeping guard dogs before leaving them to their fate.]]
** [[spoiler:Marshall does this to black Doug after he frees the Wolfpack from the Mexican authorities. He claims that his head of security isn't doing his job if a bunch of guys managed to break into the villa and steal the gold.]]
