Manah manah!

You know that song they use in a Diet Dr. Pepper commercial? It goes "Manah manah, doo dooooo doo doo doo!" Well, I'm watching the first season of the Muppet Show, and it's a song they sang in the VERY FIRST SKETCH of the show! It's a hairy muppet guy singing the manah manah part, and two horned female muppets singing the doo doo part. I'm pretty sure the original lyrics were "monage et 'trois" "no noooo, no no no!" You be the judge
