Three Legged chicken

Guy: "Hey, you might not believe this, but I just saw a three-legged chicken bolt into your barn over there." Farmer: "Oh, yeah, that's my chicken alright! I've got a dozen of 'em!" Guy: "Why in hell do you raise three-legged chickens?" Farmer: "Well the idea is, I like chicken legs, my wife likes chicken legs, and my son likes chicken legs. So when we sit down for a meal, we all get a leg!" Guy: "Jeez, that's some good thinking. So how do they taste?" Farmer: "Fucked if I know! We haven't been able to catch one yet!"
