My sister and I have been singing the song from the Muppets all week -- the one that starts off with the guy bellowing, "Mahna Mahna!" So I resolved to search it on youtube and see the original.
"How are you going to find it?" she asked. "By searching for 'mahna mahna'?"
"Sure," I said. And lo and behold, when I started typing "muppets", youtube offered me a variety of options, the second of which was "muppets mahna mahna". So without further ado, here's "Mahna Mahna".
