Oscar Weil and Benjamin Oppenheimer are Jews, and were sitting in a Chinese restaurant in Shanghai.
"Oscar," asked Benjie, "Are there any Jews in China ?"
"I don't know," Oscar replied. "Why don't we ask the waiter?"
When the waiter came by, Benjie asked him, "Are there any Chinese Jews here in Shanghai?"
"I don't know sir, let me ask" the waiter replied, and he went into the kitchen.
He returned in a few minutes and said, "No, sir. No Chinese Jews."
"Are you sure?" Benjie asked.
"I will check again, sir" the waiter replied and went back to the kitchen.
While he was still gone, Oscar said, "I cannot believe there are no Jews in China, our people are scattered everywhere."
When the waiter returned he said, "Sir, no Chinese Jews."
"Are you really sure?" Benjie asked again. "I cannot believe there are no Chinese Jews."
"Sir, I asked everyone," the waiter replied exasperated. "We have orange Jews, apple Jews, tomato Jews and grape Jews, but no one ever hear of Chinese Jews! If you want, we have Chinese Tea."
