(This is a filthy,perverted joke! I laughed but that has nothing to do with my disgust at filthy perverted jokes!)

A guy, a pig and a dog are the only survivors of a shipwreck. They are washed up on a deserted island. The three manage to survive together and after some time settle down together.

One evening as the tropical sun is setting and they are sitting on the beach together looking out at the romantic sunset - the guy gets some romantic feelings for the pig. He puts his arm around the pig. Immediately, the dog growls at this and the guy hurriedly takes his arm away from the pig.

Some days more pass -and a stunningly gorgeous woman is washed ashore -another survivor of a shipwreck. Everyone takes to her - particularly the dog.

A while later all of them are sitting on the beach and watching another beautiful sunset. The guy leans over to the gorgeous woman and whispers in her her ear " Could you take the dog for a walk?"

Good one
