During the first day of Hanukkah, two elderly Jewish men were sitting in a wonderful deli frequented almost exclusively by Jews in New York City. They were talking amongst themselves in Yiddish, the colorful language of Jews who came over from Eastern Europe.
A Chinese waiter, only one year in New York, came up and in fluent, impeccable Yiddish asked them if everything was okay and if they were enjoying the holiday.
The Jewish men were dumbfounded. "Where did he ever learn such perfect Yiddish?" they both thought. After they paid the bill, they asked the restaurant manager, an old friend of theirs, "Where did our waiter learn such fabulous Yiddish?"
The manager looked around and leaned in so no one else could hear and said, "Shhhh. He thinks we're teaching him English."
