A friend turned me on to the awesome amount of old Sesame Street clips on You Tube. I haven't watched Sesame Street since a lot of these made their original television appearance, but they're all brilliantly inspired -- funny enough for adults while (I guess) teaching kids how to read. Hey, it worked for me, right?
My current fav -- how I still feel about food to this day.
Cookie Monster at the disco, spoofing Isaac Hayes' theme from Shaft. "Cookie? Me so 'ooooongreeee."
And this, while not from Sesame Street but the equally brilliant Muppet Show, remains one of the funniest things I've ever seen.
How I love Animal. *Sigh*
