This movie was in every way shape of form one of the funniest movies that follows the effects of drugs and alcohol. This film made me laugh to the point where i was crying. When i first heard about this movie before it was released in theaters i said 'It will be a mediocre piece of work" but when i viewed the movie in theaters i was dead wrong. This movie had the funniest and clever plot i have ever seen a movie with this type of genre have. Plus i had known Zach Galifianakis  from previous films but he played relatively small parts in the movies. In this movie Zach G really lets you know how funny and what a comedian he really is. The plot of this film is hysterical, Four guys named Doug, Stu, Phil and Alan decide to visit Las Vegas due to the fact that Doug who is played by Justin Bartha is getting married and wants to visit Vegas for a bachelor party. The four men embark on their journey while escaping their own lives at home in the process. To quote what Justin Bartha's character says in the film he says as the men are taking a shot on top of the hotel roof "To a night we will never forget". This quote is hilarious because in the scene immediately after that three of the guys wake up in their hotel sweet with major damages done to the room, Stu played by Ed Helms with a missing tooth, a baby in the closet with nos signs of a mother, a chicken, a tiger in the bathroom and a missing friend named Doug. Alan, Stu and Phil must try to reconstruct their memory of the night before so they can find their missing friend, solve their problems and get Doug back home in time for his wedding. The mystery as it unravels as to what actually occurred the night before is hilarious. as you progress. I loved the comments that Zach G made throughout the film because even though they were little they were still funny and made me laugh hysterically. My favorite scene in this movie is the scene in which Alan, Phil and Stu are trying to get the tiger in the bathroom back to Mike Tyson's mansion by drugging it with a steak filled with sleeping pills. The scene was even more funnier because of several things. One is that Stu begins to sing about Doug which is funny and if you listen closely in the background you can hear the tiger make a noise and drop on the floor plus Stu's actions while feeding the steak to the tiger. This movie is funny and has a very funny unforgettable ending. I loved that they showed the pictures of what actually happened the night before at tthe end because that made the movie even more funny. Please view this hilarious film from the director of OLD SCHOOL.
