I have watched many comedy short subjects over time... about half of the different Columbia shorts lineups (Stooges, Harry Langdon, El Brendel, Shemp Howard, Walter Catlett, etc), Laurel & Hardy, Buster Keaton, Billy Bevan, etc. They all pretty much have some slapstick element, although some of them not-so-much.
What I have noticed, however, is that the Stooges are alone in the true violence. The head bonks, the eye pokes, the saws on the head, etc. Once in a while a tool will break on someone's head in a Schilling/Lane or a Vernon/Quillan short, but otherwise this kind of slapstick is absent. Were these things unique to just the Three Stooges, or have I just not watched the right short subjects to see that kind of thing?
I'm just curious, as most of these guys are still hilarious in their own ways.
