|A man who has been shipwrecked on a desert island for several years is beginning to feel the effects of being starved of sex for so long. However, the only living creatures on the island are a pig and a dog.
One day, the man decides that he's had enough and thinks to himself that it has to be the pig.
But when he approaches the sow for his moment of passion, the dog bites the man's backside.
This continues for several days, and the man is beginning to get very frustrated.
But one morning, the man's luck changes: out at sea, he notices a beautiful young woman on the point of drowning.
He swims over, drags her out on to the beach and proceeds to give her the kiss of life.
The woman comes to and is very grateful.
"Thank you very much, " she says. " I will do anything for you, and I mean absolutely anything!!"
The man can't believe his luck and quickly replies, "Taking that fucking dog for a walk!!"
