Pee-Wee's Playhouse (1986-1991) is a highly acclaimed children's television series combining live action, puppetry, and animation, starring Pee-Wee Herman, the fictional alter ego of Paul Reubens. The series had its roots in Reubens' stage shows, and a more adult 1981 special The Pee-Wee Herman Show was the first attempt to bring the playhouse to television. Pee-Wee himself guest starred on Sesame Street, on his playhouse set and surrounded by the show's puppet characters, in an alphabet insert and in the celebrity version of "Put Down the Duckie".
