Slim and shorty decided to rob a train. As they're riding up, Slim's a little quicker and
as he jumps up and into the front of the passenger car he hollers, "This is a holdup. We're going to rob all the men and rape all the women!" Shorty, being a little slower jumps on the train and in the back of the passenger car and hollers, "this is a holdup. We're going to rob all the men and let all the women go!" To which a little old lady in the seat next to Shorty says: "Shut up shorty; Slim's arobbin this train!"
