One day a bachelor who was a poor tipper walked into his favorite restaurant and ordered lunch.

A new waitress served his meal and received a three cent tip.

When he came in the next day, she thanked him for his "generosity" and she said she could tell the character of a diner by the way he tipped.

"Well, what could you tell about me?" he asked.

"You put three pennies in a neat row," said the waitress, "and that shows you are a very tidy person. The first penny tells me you are a frugal, and the second tells me that you are a bachelor."

"That's true," he agreed. "But what does the third penny tell you?"

"The third penny tells me your Father was a bachelor, too."
