A feed salesman is on his way to a farm. As he's driving along at forty m.p.h., he looks out his car window and sees a three-legged chicken running alongside him, keeping pace with his car. He is amazed that a chicken is running at forty m.p.h. So he speeds up to forty-five, fifty, then sixty m.p.h. The chicken keeps right up with him the whole way, then suddenly takes off and disappears into the distance. The man pulls into the farmyard and says to the farmer, "You know, the strangest thing just happened to me; I was driving along at at least sixty miles an hour and a chicken passed me like I was standing still!" "Yeah," the farmer replies, "that chicken was ours. You see, there's me, and there's Ma, and there's our son Billy. Whenever we had chicken for dinner, we would all want a drumstick, so we'd have to kill two chickens. So we decided to try and breed a three-legged chicken so each of us could have a drumstick." "How do they taste?" said the farmer. "Don't know," replied the farmer. "We haven't been able to catch one yet."
