A mohel was retiring, so his community threw him a party. His bumistant brought him a small box, which he opened, and inside was a wallet. The bumistant explained that the wallet had been made from all the foreskins the mohel had cut over the years. Shocked, he wondered aloud why so many foreskins would only make something as small as wallet. The bumistant replied”I don’t know, but if you rub it, it becomes a briefcase.”
