Crazy Harry

From Freepedia

Crazy Harry was a Muppet with an explosives fixation, who appeared in The Muppet Show and was performed by Richard Hunt. He had scruffy hair and an uncombed beard and huge baggy eyes. Early in season one he played triangle with the pit band. He usually carried a plunger box which would activate a hidden charge, often to his victim's chagrin. Once he assisted Gonzo in a cannonball-catching act, but perhaps overdid it on the powder, which resulted in absurdly-stretched arms for the beak-nosed weirdo. In ep #28 he provided the "Ra-ta-ta-ta-ta!" chorus of "Chanson D'amour", happily blowing the stage and performers to smithereens with his little plunger and cackling.
