Reward

A lady lost her handbag in the bustle of shopping. 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 20 $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.”
