Well I did love that thread until Tunes posted this:

(1968), a pseudo-documentary film about wild sexual activity and other behavior in Sweden ("Mah Nà Mah Nà" accompanied a scene set in a sauna).
The song became familiar to many from its renditions by the Muppets on national television. On November 30, 1969, "Mahna Mahna" was performed on the The Ed Sullivan Show by a Muppet also known as Mahna Mahna, and the Snowths. Also in 1969, "Mahna Mahna" was performed on Sesame Street by a character that was later known as Bip Bipadotta, along with two Anything Muppet girls.
Many thanks to DoonDoon for getting this damn thing stuck in my head!
which was all well and good by itself until I was watching a music quiz show with the family (parents, grandparents, assorted relatives). A question came up about the origin of that very song. I immediately cried out the correct answer (the quiz show agreed with me) and then had to spend the rest of the night convincing the relatives that I knew the answer from a friendly forum and did not actually watch the softcore porn video.
