My vote goes to Revenge of the Virgins, a topless cowboy/indian western made in 1959.. A band of topless virgin female Indians knock of a group of absolutely dumber than dog crap prospectors.. Theyre so dumb they deserved to get drowned in mothers milk, but they didn't in this one. One highlight is when one guy gets shot in the back of the head, but a gold coin in his vest pocket saves him. What the pocket might have POSSIBLY be doing there is anyone's guess and it's not there when he gets shot, but hey..anything can save your life in the worlds dumbest movie..right?
