TWO HILLBILLIES FIND SHEEP

Two Hillbillies were hunting with no luck. Then one of them saw a sheep with its head caught in a fence. One hillbilly looks at the other and says, "Let's have sex with the sheep."
The other one said, "ok." So when the first Hillbilly is done he turns to second hillbilly and says, "Your turn." So the second one sticks his head in the fence.
