A welshman gets washed up on a desert island with just a sheep an a collie dog for company. After a few days the welshman starts to feel a little frisky and starts eyeing up the sheep. The collie dogs instincts kick in and it won't let him anywhere near the sheep. The following morning, to his delight a beautiful woman is washed ashore. "You've saved my life" say's the welshman, "can you take this f*cking dog for a walk".
