The Pitch for The Muppet Show
Wow. Here's the original pitch Jim Henson made to sell The Muppet Show to CBS. It's a slow build -- things only start getting wacky around the one-minute mark, but go completely nuts by the end. This is brilliant. According to Muppet Wiki, there was a little clip at the end that was edited out of this video (this version likely came from a DVD extra):
After Leo's powerful speech, Kermit appears from off-screen against a CBS logo and shrugs, "What the hell was that all about?"
My favorite little gem: the depiction of "Kermit's mother" as "Whistler's Mother," near the end.
