A farmer buys a young rooster. As soon as he gets it home it bangs all 150 of the farmer's hens. The farmer is impressed. Later in the afternoon it bangs all 150 of the hens again.

The next day after banging the 150 hens it starts screwing ducks and geese on the farm too.

Later that afternoon the farmer finds the rooster laying in the middle of the barnyard passed out and almost dead with vultures circling overhead.

The farmer looks down at him and says "You deserved it, you horny little bastard."

The rooster opens one eye, points up at the sky and says "Shhhh ... they're about to land!"
