Either that type of humor appeals to you or it doesn't. The Stooges were slapstick masters with precision timing. They also had good chemistry with each other, including Shemp, and knew how to get the most out of various situations. As comedic actors, they could walk into a certain environ and say "ok, what can we fuck up and how bad can we fuck it up." I don't watch them diehard, but like and appreciate them.
