The Hangover

To celebrate his upcoming marriage to Tracy Garner, Doug Billings travels to Las Vegas with his best friends Phil Wenneck, Stuart "Stu" Price, and Tracy's brother Alan, in Doug's future father-in-law Sid's vintage Mercedes-Benz W111. They spend the night at Caesars Palace, where they relax in their hotel suite before celebrating with a few drinks on the hotel rooftop. The next morning, Phil, Stu, and Alan awaken to find they have no memory of the previous night. Doug is nowhere to be found, Stu's tooth is in Alan's pocket, their suite is in a state of complete disarray, a tiger is in their bathroom, a chicken is in their living room, and a baby is in the closet, whom Alan names "Carlos". They see Doug's mattress impaled on a statue outside of Caesars Palace and when they ask for their Mercedes, the valet delivers an LVPD police cruiser.
