Cousin Eddie
Cousin Eddie, portrayed by Randy Quaid, is a memorable character in the 1989 film National Lampoon's Christmas Vacation, where he arrives unannounced at the Griswold family home, causing chaos with his obnoxious behavior and a malfunctioning Winnebago. His arrival is a central comedic element, with his RV visible in the driveway during the house light-up scene before his family's surprise appearance.
