A man is stranded on a desert island with a sheep and a dog.
The only survivors of a shipwreck.
After a few months, the sheep starts looking really attractive to the man.
However, whenever he approaches the sheep the dog begins to growl in a threatening manner.
The man takes the dog to the opposite side of the island giving it some food as a distraction.
He runs back to the sheep only to find the dog was already there.
The man ties the dog to a tree with a lpeice of rope.
He goes back to the sheep only to find the dog growling with a gnawed off rope around its neck.
By now, the man is getting depressed and frustrated.
As he sits under a palm tree staring out to sea, he spots something floating in the water.
There seems to have been another shipwreck, the only survivor, a beautiful woman.
She asks him who he is and, taking pity upon his lonely state, asks if there's ANYTHING she could do for him.
The man thinks for a moment and then responds: "Could you take the dog for a walk?"
