A man gets shipwrecked on a desert island. His only companions in the boat are a pig and his dog.
After a few weeks, he's been pretty successful - built
himself a shack and doing OK for food. The only problem, is that he's really starting to miss sex.
He looks at the options open to him and looks at the dog and the pig. "Got to be the pig", he thinks.
So, he starts screwing this pig and all of a sudden, the alsation bites him on the arse. Bloody hell, he thinks - this isn't on. The next day, he tries again - dog sinks his teeth into his arse again.
Man goes for walk on seashore, trying to think what he's going to do about this. He comes
across a young woman, looking in a bad way, lying on the beach. He carries her back to his shack and spends the next week or so looking after her and getting her back to health.
After a week, she finally comes around and says to him "I am just so grateful for what you've done - anything I can do for you, just name it".
"Hmmm, he thinks", looking at this beautiful young thing lying two feet from him.
"Well, there is something", he says somewhat nervously.
"Yes, name it -
anything at all - I'm yours."
"OK, can you take this damn dog for a walk?"
