Paul Reubens [SEP] Introduction
Paul Reubens (; né Rubenfeld; born August 27, 1952) is an American actor, comedian, writer, and producer. He is best known for his character Pee-wee Herman. Reubens joined the Los Angeles troupe The Groundlings in the 1970s, and started his career as an improvisational comedian and stage actor. In 1982, Reubens began appearing in a show about a character he had been developing for years. The show was called "The Pee-wee Herman Show", and ran for five sold-out months; HBO also produced a successful special about it. Pee-wee became an instant cult figure and, for the next decade, Reubens was completely committed to his character, doing all of his public appearances and interviews as Pee-wee.
