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 Braniff sign at the end of the credits was used for fun in the first episode. Braniff is originally an airline. Trey and Matt got permission to use the sign for every episode.
Canadian broadcasts on commercial TV include a disclaimer warning of adult content -- which is immediately followed by "South Park's" own tongue-in-cheek version.
In the episode "Mr. Hanky", there is a short clip of Jesus singing to himself on his birthday during the credits.
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 precisely what I mean, when I say its a Shpadoinkle day!"
If the characters sing a song in the episode, it is almost always played over the end credits.
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.
Season Six has Timmy fill in for Kenny in singing the theme song since Kenny was absent for that season.
The season 1 episodes have three different versions of credits. They can be distinguished by the copyright date at the end, the first version has a 1997 or 1998 copyright date at the end, the second (incorrectly) has a 2000 copyright date and the third version, which is found on the DVD releases, has no copyright date at all.
