I love Buster Keaton! I watched Go West (1925) on Sunday, and it was wonderful. He shoots a tiny little gun at the bad guy, who merely grabs his buttocks and says "Ouch" in response. At another time, he says something to another bad guy, who says "When you say that--smile." Of course, Buster doesn't smile, so he pushes up the corners of his mouth with two fingers.
