A guy gets shipwrecked on an island with only a dog and a pig to keep him company.
He builds a shelter, and there is plenty of fish, and lots of tree dead fall to build cook fires. He settles in to a routine, but after about 5 or 6 months, the little pig starts to looking good.
He controls himself for as long as he can, but one night he can't help himself. He scoots over to the pig and starts stroking her back and rubbing her feet, when all of a sudden the dog viciously attacks him.
He knocks it off, and sulks away, ashamed of himself.
Several more months go by, and the guy just can't hold out any longer. He checks to make sure that the dog is sound asleep, tiptoes over to the pig, and begins his overture. Sure enough, the dog wakes up and attacks him even more violently than before.
A couple of more months go by, the guy just spends his days sulking and pondering swimming out to sea to die.
There's a huge storm, and the next morning, a drop-dead gorgeous, world-class beautiful woman washes up to the beach clinging to some flotsam.
The guy gets down on his knees weeping, thanking his diety of choice for his good fortune.
He walks up to the woman and says, "Say... Would you please do me a favor? Hold this dog for me for a while!"
