The Hangover was one of the biggest movies of this past year, and is scheduled to be put out on dvd by the end of this month. This movie is about four friends who are taking a trip to Las Vegas before their best friend is to get married. These four guys run in to more trouble than you could ever imagine that they would, and they even have a run in with the famous boxer Mike Tyson. They end up taking some pills that they thought were some drugs that they wanted, but ended up making the guys lose their memory.
