Two elderly Jewish men were sitting in a deli frequented almost exclusively
by Jews in New York City. They were talking amongst themselves in Yiddish.
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 will hear and said,
"Shhhh. He thinks we're teaching him English."
