Mine is of course the Almighty
Cantus. The Wise, bold, and forever well-spoken Fraggle of the Minstrels. My other favorites are:
Dr. Teeth - My Second fav. Muppet. Forever groovey! The rest of the Mayhem are all very cool, but Teeth...he's just it for me.
Yorick (from Sam and Friends) - After seeing the "I get So Hungry" Scetch at the Museum of Radio and Television in LA, I was hooked
Statler and Waldorf - Possibly the greatest comedic duo ever.
Beaker - What's not to love? I think he was so funny in Muppet*Vision. Beaker Rock!
...and every other Muppet ever. What can I say? A Muppet is a Muppet, and I love them all
