Ranked #10 in TV Guide's list of the "25 Top Cult Shows Ever!" (30 May 2004 issue).
The theme song was sung by Cyndi Lauper, but is listed in the credits by a stage name, Ellen Shaw.
It is often assumed that the main reason for the cancellation of the series was Paul Reubens indictment for obscenity for an incident in an adult theater in Florida, but in fact Reubens and CBS had mutually agreed to end the show in 1991. CBS did, however, choose not to air the reruns of episodes they had planned for August of that year, and the final network telecast was 27 July 1991.
It is rumored that the concept for the show actually came from Andy Kaufman with his co-writer Bob Zmuda, who dubbed it "Andy's Funhouse," based on Kaufman's experiences doing children's birthday parties and performing for children. In an Onion AV Club interview Reubens refuted this rumor, stating, "I've heard that a lot, but I don't know where that came from, actually. Andy had 'Andy's Funhouse' around the same time. I saw it performed - I was this huge Andy Kaufman fan. But no, we were just both doing kids' shows. When I look back at them now, I think what Andy did wasn't really similar to what I did."
Rob Zombie was a production assistant on the show.
John Singleton was a security guard on the Playhouse set.
