Almost exactly thirty seconds later, after swimming through a series of tubes (no, I’m not going to stop making fun of Ted Stevens until that corrupt idiot is expelled, indicted, or dies) I had my answer. Thank you, Intertron!
Although the song “Mah Nà Mah Nà” was included in a Sesame Street skit in 1969 prior to being performed by Muppets on The Ed Sulivan Show and then performed again for The Muppet Show, it was actually taken from a movie called Sweden: Heaven and Hell. This film was an Italian pseudo-documentary that claimed to record the wild sexual antics of Scandinavian teens.
That’s right, kids: “Mahna Mahna” is a song from a soft-core porno.
Now that you know… Enjoy!
