I’ve got a good joke.
An American Jew goes to a kosher restaurant in the UK. He is being served by a Chinese waiter, who spoke to him in perfect Yiddish, offering him his menu. After the meal the American Jew turns to leave and sees the manager smiling at him, asking, “Did you like the meal?” The American Jew says: ‘Thanks, I really enjoyed it. And by the way I was really surprised at your Yiddish-speaking waiter.” The manager replied “Oh that’s nothing. He thinks he is speaking English.”
