A rabbi had performed numerous circumcisions during his tenure and saved every foreskin in a Mason jar. Once it was full, he took it to a tanner and asked if he could make something out of them. The tanner said he’d see what he could do.
Three weeks later, the tanner calls the rabbi and tells him he’s finished, so the rabbi goes to his shop. The tanner presents him with a wallet.
“After all those years, all you could make out of all those foreskins was a wallet?” the rabbi asks.
“Not just a wallet,” replies the tanner. “If you rub it, it turns into a suitcase!”
