How about my reward?

A sweet old lady dropped her handbag during the hustle and bustle of holiday shopping.  An honest, little boy noticed her drop the handbag, so he picked it up to return to her. The lady looked into her handbag and commented, “Well, that’s funny.  Before I dropped my bad, there was a $20 dollar bill in it.  Now there are twenty $1 bills.”

The boy quickly replied, “That’s right, lady. The last time I found a purse, the owner didn’t have any change for a reward.”
