Smith and Jones were sitting in a Chinese restaurant. "Smith," asked Jones, "are there any Jews in China?" "I don't know," Smith replied. "Why don't we ask the waiter?" When the waiter came by, Jones asked him, "Are there any Chinese Jews?" Waiter: "No Chinese Jews, Sir." "Are you really sure?" Jones asked again. "I cannot believe there are no Chinese Jews." The waiter replied exasperated, "We have Orange Jews, Prune Jews, Tomato Jews and Grape Jews, but we have no Chinese Jews."
