The Hangover Part II (2011) NTSC WS [ctang]

Dentist Stu Price is getting ready to marry Lauren in Thailand and his best friends, Doug Billings, Phil Winnick, and Alan Garner travel there for the wedding. After the dinner party, Doug, Phil, and Alan invite Stu to drink beer around a beach bonfire with Lauren's teenage brother Teddy; Phil brings the beer and marshmallows. The next morning, Phil, Stu, and Alan have hangovers and can't recall the night before; their room is a shambles; Teddy is missing but a little monkey is in the room; Teddy's finger is in a glass of water, Alan's head is shaved, and Stu has a tattoo on his face. As the trio start trying to figure out what happened, they discover Mr. Chow on the floor under the carpet. They learn that they are in Bangkok, and Mr. Chow is about to explain everything about the night before--but insists on snorting cocaine first, which puts him out of commission and Phil, Stu, and Alan to unravel their crazy night themselves--and find Teddy.
