You know, I just traveled all over Europe and I was surprised by all the Jews - French Jews, German Jews, Polish Jews ... can you tell me, do you have Japanese Jews ?
Waiter: One minute sir, I go ask ...
A few minutes later, the waiter returns
Waiter: I sorry sir, we have grape juice and orange juice, but no Japanese juice ...
