An old man and a young woman fall in love and get married. their relationship is wonderful, except for the sex; she is unable to reach orgasm, and as everyone knows, sexual fulfillment is written into Jewish law as a marital duty, so they go talk to the rabbi. After listening to the explaination of the situation, the rabbi proposes a solution. He tells them to find a strapping young man in the village, and have him wave a towel over the couple as they are having sex. The husband and wife are sceptical, but the rabbi's wisdom has not failed them in the past, so they put the plan into action. It doesn't work, however, and they return to the rabbi, still frustrated. Unperturbed, the rabbi tells them not to worry, and that the solution to their problems needs only one small adjustment; the old man is to wave the towel while the strapping lad has sex with the young wife. The couple is still sceptical, but when they try the modified plan, it works! the woman achieves an earth shattering orgasm, at which point the old man leans over to the young lad and says "now THAT'S how you wave a towel!"
