Germy Shoemangler sez, "On the Kraft Music Hall, Harpo plays the clarinet (and blows bubbles out of it), accuses Milton Berle of using cocaine, and holds up seven fingers on one hand when asked how long he's been playing the clarinet. A surreal moment in late '50s TV.
Harpo was over seventy years old when he made this appearance, and he was younger than ever."
It's true: Harpo was always the embodiment of anarchy: funny, relentless, and steadfastly unserious. If I can't honk, I don't want to be a part of your revolution!
(Thanks, Germy Shoemangler!)
