As retold by Bruce Lowitt

Two men, one Jewish, the other Chinese, are discussing their heritages.

The Jew comments on what a wise people the Chinese are.

"Yes," the Chinese man says, "Our culture is over 4,000 years old. But, you Jews are a very wise people, too."

"Yes," the Jew says. "Our culture is over 5,000 years old."

The Chinese man is stunned. "Impossible," he says. "Where did your people 
eat for a thousand years?"
