The neighbour says, "You can have this rooster. His name's Roy. He'll get all your hens pregnant. He's a real stud."
So the farmer takes him home and says, "It's your first day so take it slow, okay?"
The farmer puts Roy in the hen house and then hears all the hens crying and yelling. Roy nailed every one of those hens and then nailed a duck and a goose at a pond.
The next morning the farmer finds Roy lying dead with his legs sticking in the air and buzzards circling overhead.
The farmer says, "Oh Roy, did you have to die?"
