Ever heard of the comedic stylings of Larry Griswold? Me either. Unfamiliarity is part of what made this clip of him performing in the 50s (on The Frank Sinatra Show) so incredible. Well, what's he's doing is incredible, whether you've heard of him or not.
Griswold was known as the "diving fool" and is credited as being involved in the early development of the trampoline. Why isn't this guy better known? That's physical comedy on par with Keaton and Chaplin!
