Even Broderick Crawford's loaded revolver seems safe compared to what Buster Keaton used to go through. (Sorry about the era inappropriate background music in this video, but Keaton's voice is in the soundtrack giving narration, so I used this clip.) If you like this kind of stuff, also check out Harold Lloyd, who Buster mentions in the narration. He was just as crazy.
