|Mr. Greenberg was an illiterate immigrant, but he worked hard, saved his pennies, and started a small business. It did well, and soon he had enough money to send for the wife and children.

Greenberg looked embarrassed. "I'm sorry about making trouble, he said, "but my wife said that since I'm now such a high-class rich guy, I should have a middle name!"
