 After years of daytime syndication, the game show returns to prime time tonight as Jimmy Kimmel hosts the 25th anniversary. We've got two celebrity contestants in the hot seat working to win big money for charity. This year's celebrity pairs include John Stamos with Dave Coulier, Rosie O'Donnell with Lisa Ann Walter, and tonight's episode with Keenan and Cal. We're making a good team because we've known each other for a long time. A long time.
