A man and his dog are shipwrecked onto a deserted island. After a few days he decides to reconnoiter the island. He discovers that the only other inhabitants are sheep. He recalls how his farm buddies would brag how they would screw sheep for kicks and he says to himself: 'I'll never be that desperate.'
Sooooo, a few days later he can't get those sheep out of his mind, and soon he's sneaking up on the flock. Just as he is about to pounce on a really cute one, the dog grabs his leg and won't let go. He snaps to, and thanks the dog for keeping him from making a fool of himself. This same scene happens every night for a month and the guy is really getting pissed at the dog.
Suddenly one day, the man spies a liferaft bobbing in the surf. In the raft is a beautiful young girl, half dead but alive. He takes her back to his hut revives her and nurses her to health. After a few days the girl is feeling fine, and that evening a rush of gratitude sweeps over her....
She confronts the man: 'I owe you my life. I'm yours forever. I'll do anything you want'
'OK, hold that dog for ten minutes!!!'
