Back in summer camp, when a few of us first started listening to Metallica and really getting into heavy metal, we made up a spoof of Master of Puppets by making it into "Master of Muppets"...here's as much of it as I can remember:
 

End of Fraggle Rock
Doozers eat their clocks
I'm your source of animation
Hands that go up necks
Moving Kermit's legs
It was fun before masturbation

Trust us you will see
More is all you need
Dedicated to
How Miss Piggy's eating you...

Come crawling faster
Obey your Master
Your life burns faster
Obey your Master
Henson!

MASTER of MUPPETS I'm pulling your strings
Waving your arms and moving your legs
Guided by me, you can't see a thing
Just call my name, `cause I'll hear you laugh
Henson!
Henson!
Just call my name, `cause I'll hear you laugh
Henson!
Henson!
