A man and his wife went to a kosher delicatessen. To their surprise their waiter, who was Chinese, took their order in Yiddish. The man could hardly believe what he was hearing. On the way out his wife asked the owner of the delicatessen where in the world did they ever find a Chinese waiter who could speak Yiddish. "Ssssshhh," said the owner, "he thinks we're teaching him English!"
