Many Years Ago

When I was a youth, watching Saturday morning cartoons, they had these "Schoolhouse Rock" PSA's in between shows. This one is the reason to this day I have the Preamble memorized, but I have to sing it in my head. They might still run PSA's on Saturday mornings, but they are probably about global warming, or being green, or some such crap. On a different note, this one must be the reason I like cheese so much.
