I have to resort to a bootleg video today. There are several different versions of this song on sesamestreet.org, but for some reason they don't have the Bert & Ernie version available through official online channels. They do have it officially available on the Old School Vol. 3 DVD set, the best of the Old School series in my somewhat biased1 opinion.

I specifically remember watching this one with my mom when I was little, and I remember that we both got a really big kick out of it.
