In the episodes 'Do the Handicapped Go to Hell?' and 'Probably', the credits say both Gary Nicholson and Jack Oldman did the voice for Satan's new boyfriend Chris. But it was neither Nicholson nor Oldman who did the voice. It was Dian Bachar, who was in Baseketball, Orgazmo and Cannibal with Trey Parker and Matt Stone.
This warning appears at the beginning of every episode: ALL CHARACTERS AND EVENTS IN THIS SHOW--EVEN THOSE BASED ON REAL PEOPLE--ARE ENTIRELY FICTIONAL. ALL CELEBRITY VOICES ARE IMPERSONATED.....POORLY. THE FOLLOWING PROGRAM CONTAINS COARSE LANGUAGE AND DUE TO ITS CONTENT IT SHOULD NOT BE VIEWED BY ANYONE
The tune used for the Braniff logo at the end of the credits is the opening song from Trey Parker and Matt Stone's first film, "Alfred Packer: The Musical" (aka Cannibal: The Musical). Titled "Shpadoinkle Day". "The Sky is blue, and all the leaves are green. The Suns as warm as a baked potato. I think I know exactly what I mean, when I say its a Shpadoinkle day!"
Before the theme song, there is always an official-looking message that says the show has adult content, "all celebrity voices have been impersonated...poorly" and that the show should not be viewed by anyone.
