Mulla and the town mayor were at the public bathhouse. As the mayor was washing up, he asked, "Mulla, if I were just a regular slave on the market, how much do you think I'd be worth?" Mulla thought about it and said, "Ten bucks." The mayor was insulted. "Are you an idiot? Just the towel I'm wearing is worth ten bucks!" Mulla nodded. "I know. That's exactly what I was pricing. You yourself are worthless."
