Q: What's with the Braniff Airlines bit at the end of each episode? Believe it?
A: I believe I've answered this before, but I'll do it again...for laughs. When Matt and Trey delivered the pilot to Comedy Central, they didn't have a bumper (you know, that card at the end of the show that tells you who created it).
Not having an appropriate company name or logo to use (Avenging Conscience notwithstanding), they tossed in the logo of Braniff Airlines - a defunct airline from the 60s and 70s - the music is the melody from "Cannibal." After the show aired, they were contacted by a company that owned the rights to the Braniff name and logo. An agreement was made to allow them the use of the logo on South Park broadcasts, but not on any other projects in the future.
Let that be a lesson to you kids. Always consult your lawyer.
И еще:
A portion of an old Braniff advertisement with a Boeing 727 appears after the end credits (where production company logos normally go) of every episode of South Park. However, in 2001, the New York Trust that still owns the Braniff Trademarks informed South Park Studios not to use Braniff in any other formats. The 12-note riff played on top of this ad during earlier South Park episodes is from a song, "Shpadoinkle Day" from Trey Parker's collegiate film project, "Alferd Packer: The Musical" (later filmed as Cannibal! The Musical). The lyrics associated with those notes are "The sky is blue/and all the leaves are green."
