Avram Kaplowitz goes to his favorite kosher restaurant on the Lower East side to have a _bissel_ tongue in raisin sauce. He is surprised to see, instead of another elderly Jew waiting on him, a Chinaman.
Avram is not pleased. While he speaks five languages – Yiddish, Hebrew, Polish, Russian and English – his English is weak and he knows almost no Chinese. Imagine his happy surprise when the Chinese waiter asks him for his order in fluent Yiddish!
Avram chats with the waiter, gives his order and eventually finishes his meal.
While paying his bill, he says to the cashier: “You know, I never heard of a Chinaman speaking Yiddish before.”
“Shah!” says the cashier. “He thinks he’s learning English.”
