Best friends Jesse and Chester awaken with hangovers and no memory of the previous night. The television is on, showing an Animal Planet program about how Tool use by animals. Their refrigerator is filled with containers of chocolate pudding, and the answering machine contains an angry message from their twin girlfriends Wilma and Wanda as to their whereabouts. They emerge from their home to find Jesse's car missing, and with it their girlfriends' first-anniversary presents. This prompts Jesse to ask the film's titular question: "Dude, where's my car?"
