chunk: To celebrate his upcoming marriage to Tracy Garner, Doug Billings travels to Las Vegas with his best friends Phil Wenneck and Stu Price, and Tracy's brother Alan, in Doug's future father-in-law's vintage Mercedes-Benz. They spend the night at Caesars Palace, where they relax in the room 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, and Doug is nowhere to be found. Stu's tooth is in Alan's pocket, their hotel suite is in a state of complete disarray, a tiger is in their bathroom, a chicken in their living room, and a baby is in the closet, whom they name "Carlos". They find Doug's mattress impaled on a statue outside of their hotel and when they ask for their Mercedes, the valet delivers an LVPD police cruiser.
