A M*******y fan gets washed up on a desert island. For months his only company was a dog and a pig. Being isolated, every now and again he would get the "urge" and attempt to fuck the pig, but every time he tried, the dog would bite him on the ankle.
Anyway, one day he couldn't believe his luck as a beautiful blonde woman got stranded on the island too. She had almost drowned trying to get ashore, but he swam out to rescue her and gave her the kiss of life. "Oh you saved my life" she says. "As a token of my appreciation, I will do ANYTHING you want me to do".
"Great" says your man, "can you bring that fucking dog for a walk"
