Pee-wee's Playhouse ran on CBS from 1986 to 1990, starring Paul Reubens as Pee-wee Herman in a surreal, toy-filled playhouse. Each episode featured a Secret Word given by Conky the robot at the start, and every character was instructed to scream whenever it was spoken. The running gag became one of the show's most quoted rituals and survived through reruns, home video and later internet clips. Online, the short scream and bell cue is now detached from full episodes and reused as a reaction to any repeated or forbidden word.
