A man is riding aimlessly through the desert on a donkey. He is not hungry or thirsty, because he has a bottomless bowl of fruit. He wanders for about a week and eventually gets pretty horny. He gets to the point where he can't stand it anymore.
So he decides to try and have s*x with the donkey.
He drops his pants and positions himself under the donkey. But, to his dismay, the donkey walks away.
Only slightly discouraged, the man decides to try again. He walks to where the donkey is standing, positions himself under the donkey, and right before he goes for it, the donkey walks away again. Now the man is getting frustrated.
As he prepares for his third and final try, he sees a vision. A beautiful, naked woman appears out of nowhere. She approaches the stunned man, who until recently, believed that he was the only person for hundreds of miles.
She smiles at him and says, "I would do anything for that bowl of fruit you have."
"Anything?" he says, getting fairly excited.
"Yes, anything." she replies.
So he says, "Will you hold the donkey?"
