A rabbi recently retired and was going through his old stuff when he found his drawer full of foreskins from all the circumcisions he had performed. Not knowing what to do with them he decided to take them to the local tailor. He told the tailor to do the best he could and make him something wonderful out of all these foreskins. The tailor said come back in two weeks and it'll be finished.

In two weeks time the rabbi came back only to be given a wallet. The rabbi asked "A wallet? That's all?" To which the tailor answered, "Yeah, but if you rub it, it turns into a suitcase!"
