An elderly man, harassed by the taunts of the neighborhood children, devised a scheme. He offered to pay them a dollar each if they would return on Tuesday and yell their insults again.
The children did so eagerly and received the money. Then he told them he would pay only 25 cents on Wednesday. When they returned, insulted him again and collected their quarters, he informed them that Thursday’s rate would be just a penny. “Forget it,” they said – and never taunted him again.
