One day a traveling salesman was driving down a country road when he was passed by a three-legged chicken. He stepped on the gas, but at fifty miles per hour the chicken was still ahead. After a few miles, the chicken ran up a driveway and into a barn behind an old farmhouse.
The salesman drove up to the house and knocked at the door. When he told the farmer what he'd just seen, the farmer said that his son was a geneticist and had developed this breed of chicken so that the, his wife and his son could each get a drumstick.
The salesman said, "That's fantastic. How do they taste?" The farmer said, "I don't know. We can't catch 'em."
