Film Analysis: The Hangover

Ordinary World:  Doug is getting married to Tracy and they are planning the wedding.  Phil is a teacher, Stu is a doctor with a crazy girlfriend named Melissa, and Alan lives at home.
Call to Adventure:  Doug, Phil, Stu, and Alan are going to Las Vegas for Doug's bachelor party. 
Refusal of the Call:  Melissa does NOT want Stu to go and is very uptight about the entire situation.  They lie to her and tell her they are going to the wine country.
Meeting with the Mentor:  After their night of partying, they lose Dough.  Phil apparently has been in the hospital ("Phil, you were in the hospital last night!" "Yeah, I guess I was." "Are you okay?!") so they visit the doctor to see if he can give them clues to where Doug might be. ("It's at the corner of get a map and ***k off. I'm a doctor, not a tour guide.")  They meet up with Eddie at the wedding chapel where he gives them clues to what really happened the night before. ("She's got my grandmother's Holocaust ring!" "I didn't know they gave out rings at the Holocaust.."
Crossing the Threshold:  Phil, Stu, and Alan lose Doug sometime during the night in Vegas and begin the journey of finding him.
Tests, Allies, Enemies:  While looking for Doug, Phil, Stu, and Alan stumble upon many clues one being that they were gambling at the Bellagio and apparently stole a man's $80,000.  This man is "Mr. Chow. Leslie Chow."  They also stole Mike Tyson's tiger, Stu got married to Jade the stripper and also pulled his tooth out, Alan finds Carlos the baby. ("Check it's collar or something.")
Approach:  Mr. Chow claims that he has kidnapped Doug and wants his eighty grand back.  Phil, Stu, and Alan come up with the idea to win his money back for him in order to get Doug.  ("Gambling? Who said anything about gambling? It's not gambling when you know you're gonna win. Counting cards is a foolproof system." "It's also illegal." "It's not illegal. It's frowned upon, like m*********** on an airplane." "I'm pretty sure that's illegal too." "Yeah, maybe after 9/11, where everyone got so sensitive. Thanks a lot bin Laden.")
Ordeal:  They have won back the $80,000.  Mr. Chow gives them back the wrong Doug who also turns out to be the one that sold Alan the drugs.  ("That is not Doug." "What are you talking about Willis? That him!" "The Doug we're looking for is white.")
Reward:  'Black' Doug helps them realize where the real Doug is and they finally find him on top of Caesar's Palace sunburned and delirious. ("I always wondered why they were called roofies, 'cause you're more likely to end up on the floor than the roof. They should call 'em floories." "Or rapies.") He also let's them know that he found $80,000 worth of Bellagio chips in his pockets. 
The Road Back:  They rush back to Doug's wedding and have tuxedos delivered to them on the road.  They make it just in time.
Resurrection:  Doug is able to salvage his relationship with his fiance, Stu finally breaks up with Melissa, and Alan is still close friends with all of them as well as trying to hit on Melissa. ("You know, I was thinking of getting my bartending license." "Suck my ****." "No, thank you.")
Return with Elixir:  Friendships are saved.  Alan finds the camera they used in Vegas.
"THAT'S CLASSIC!"
