Harvey Kneeslapper is a blonde-haired and wild-eyed Muppet in a blue sweater who always loves jokes and puns when he sees someone across on Sesame Street.
He slaps letters and numbers on any of the Anything Muppet's chests.
Harvey disappeared from Sesame Street, because some people didn't like him and his laughing was too hard.
He is played by Frank Oz.
