A farmer walks into his bedroom where his wife is lying on the bed, reading a book. The farmer picks up a sheep he had brought with him in the room and throws it on the bed.
“That’s the pig I screw when you’re not in the mood,” says the Farmer.
“That’s not a pig, that’s a sheep, “ replies his wife.
“Shut up, “ says the farmer, “I’m not talking to you!”
