These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Critical Dissonance: The sequel was largely panned by critics, but it was successful at the box office, outgrossing the original (in more then one way).
Crosses the Line Twice: A cop (played by six-and-a-half foot tall Marine, Rob Riggle) kicking in the door, pointing a gun, and screaming "SHUT THAT BABY UP!"
They were not random. They were actual equations used in probability calculation. The creators have Shown Their Work.
Don't forget Stu's CMOA when he breaks up with his bitchy girlfriend at Doug's wedding. His best line has to be, "Since you fucked that waiter on your cruise last June! BOOM!" Since quoting it doesn't do it justice, you can listen here.
Crowning Moment of Funny: Too many to mention, but Mike Tyson trying to sing "In The Air Tonight" has to be up there. His reaction to finding out that the guys drove up to his house in a stolen cop car? "NICE!"
Mr Chow pops out of the car boot, naked, attacking the main characters.
"Too-ta-loo Mutha fuckaaaaaaaa-a-a-a-a-a-a-a-ah!"
"I didn't know they gave out rings during the Holocaust."
The Rain Man shout out, especially Alan perfectly mimicking Dustin Hoffman's affectations down the escalator.
Crowning Moment of Heartwarming: Bit of a stretch, but the whole premise in a way. Most of these guys have definite Jerkass tendencies, but they'll go to some pretty extraordinary lengths to find their friend.
The scene where Stu finally breaks up with Melissa - Phil's expression as he sees this is almost like that of a proud father, whilst Doug & Tracy are grinning & hugging Stu once it happens.
Phil spends the whole movie being an irresponsible frat boy type...and is then really excited to see his family again and carries his sleeping son around for the entire end of the movie.
Crowning Music of Awesome: The soundtrack has an impressive hip-hop collection for a movie that does not specifically revolve around hip-hop.
'What do Tigers dream of when they take a little Tiger snooze?' It's beautiful.
The Dan Band's version of candy shop.
Dude, Not Funny!: Tyson's reaction to the security footage of Phil dry-humping the tiger.
Fridge Logic: Doug was severely burned after the guys found him, to the point of his chest hurting like crazy when somebody touches it. In the second movie, from the prostitute's story, we can tell that Stu, as Alan puts it, "has semen in him". Additionally, he's been treated with a needle from a not-so-reliable tattoo artist. Now, Stu is a responsible and caring guy, when he's not stoned. It's safe to assume that he'd take all kinds of tests before endagering his new wife. This means that neither of the brooms had sex on their wedding night. And you thought that ( missing fingers aside) there had been no consequences!
Hilarious in Hindsight: In the sequel, Mike Tyson tells Stu that he should have his tattoo removed. Considering the Frivolous Lawsuit over that same tattoo that nearly caused the film's delay, this also doubles as a retroactive "Funny Aneurysm" Moment.
Insane Troll Logic: The reasoning behind a Frivolous Lawsuit a month before the release of The Hangover: Part II - S. Victor Whitmill, the tattoo artist who worked on Mike Tyson's face tattoo, claims that Stu getting that same tattoo whilst drunk infringes on his copyright of the tattoo's design and the film should be banned as a result. This is despite Mike Tyson appearing in the film. While the courts found this reasoning to be quite sane, they decided to bow to public interest, and the film will indeed open as scheduled.
Sequelitis: Arguably, Part II does exhibit examples of Type I (where's Heather Graham?) and Type IV (Let's do the same thing, but in Bangkok!).
Squick: While the credits is one big Crowning Moment of Funny as a whole, there are a couple of pictures that'll make viewers want to vomit.
Unfortunate Implications: Basically how Lauren is so nonchalant and accepting of everything that Stu did the night before, including the issue with Teddy. Kind of has a Me Love You Long Time tone to it in that she's kind of Stepford-ish like that.
It's pretty obvious a lot of her and Teddy's character development was left on the cutting room floor. For example, he seems fairly unbothered by losing a finger despite being on the surgical track at a major medical school, which makes one wonder if there wasn't a Calling the Old Man Out moment he didn't get in favor of Stu. Also, a few lines of hers seem to hint that part of the reason she likes Stu is that her father absolutely hates his guts.
What an Idiot: Part II is being sued for copyright infringement over a tattoo. This is the thirdtime in several years this (a copyright infringement suit, this being the first suit anyone has filed on anyone else over a tattoo) has happened to Warner. You'd think they'd have learned by now...
The Woobie: Alan is this at some points. Especially when he starts singing "We're the three best friends that anyone could have!"
Even more so when he's genuinely distressed at the idea that Doug might be dead, while the other two don't seem to have considered the possibility.
Stu certainly considered the possibility:
Our best friend Doug is probably lying facedown in a ditch right now with a methhead buttfucking his corpse!!
Alan's Woobie status drops dramatically when you consider that nearly every bad thing that happens to the Wolfpack is his fault. Mainly because he drugs them in both films.
Stu is another Woobie. In the first film, his girlfriend controls his life with an iron fist and he not only lacks the guts to stand up for himself (until the end), but actually makes excuses for her abusing and cheating on him. In the second film, his disapproving father-in-law emasculates him in a similar fashion. And to top it all off, Alan's stupidity results in Stu being put through hell in both films and nearly having his marriage destroyed in the second.
