If you went to see the smash new Muppet movie over the weekend, then no doubt you and/or your kids have been singing "Mahna, Mahna" -- do, dooo, de, do, do -- ever since. The song is as infectious -- and potentially irritating -- as the old Menards jingle. You can hear it at 1:42 of this Muppet preview trailer on youtube. And here is a version from years ago when the original Muppet Show was on.

But did you know the scantily clad secret behind this song? An article in Slate digs out the origin of this song, reportedly from a SOFT-CORE EUROPEAN FILM! A clip of the video can be viewed below and on the Slate article. No nudity in the clip -- so it's kinda, sorta safe viewing if you're in your office -- but you get the idea.

Anyway, parents, what do we make of this? Does this change your enjoyment of the song at all? (Assuming you enjoyed it in the first place?!)
