A lady lost her handbag. It was found by an honest little boy and returned to her. Looking in her purse, she commented, "Hmmm.... That's funny. When I lost my bag there was a $20 bill in it. Now there are twenty $1 bills."

　　The boy quickly replied, "That's right, lady. The last time I found a lady's purse, she didn't have any change for a reward."
