144. The Muppets
Strange but true: The Muppets were first-season cast members. But not the funny Muppets — a dark and grumpy version, starring a lizard named Scred. Jim Henson hated the "I'm Scred and you're not" gags. So he left to start The Muppet Show. Too bad — Gonzo and Belushi would have made quite a team.
