Two guys decide to try out a new Jewish Deli in their neighborhood. A Chinese waiter approaches their table and takes their order in perfect Yiddish. The two men are utterly amazed that this Chinese waiter can speak to them in absolutely impeccable Yiddish.
The waiter returns with their food and bids them a hearty appetite, in Yiddish of course. The men eat their meal as they continue to discuss this unbelievable Chinese waiter. Finally they call the waiter over and ask him for their check. The waiter gives it to them and in Yiddish bids them farewell.
As they are paying for their meal, one of the men asks the owner, "where did you find this incredible Chinese waiter?"
The owner looks around to make sure no one else is listening and he says to them "Sha, he thinks I'm teaching him English"!!!
