Amazed, he sped up to follow, but the chicken takes off faster and faster. Finally the chicken screeches into a turn and goes into a small farm. As he turns to follow, John notices that the chicken has THREE legs.
He pulls to a stop in front of the farm house, and looking around, notices that ALL the chickens have 3 legs.
He says to the farmer "THREE-legged chickens? Thats astounding!"
The Farmer replies "Yep, I bred 'em that way--I love drumsticks."
John: "Well, tell me, how does a 3 legged chicken taste?"
Farmer: "Dunno, haven't been able to catch one yet."
