Those lovable Muppets bring back warm memories from childhood. Whether it was the 'Muppet Christmas Carol' or 'Muppet Treasure Island,' all of these faces are more than familiar. Instead of reliving your childhood, why not combine the Muppets with some death metal like this clever person did?

Edited to fit Cryptopsy's song 'Mutant Christ' off their debut album, 'Blasphemy Made Flesh,' this video is good for more than a few laughs. Beaker introduces the song in his high-pitched voice before taking on the feral gutturals of singer Lord Worm. Animal blasts away behind the kit, perfectly synced up due to some masterful editing skills. Childhood doesn't have to end!
