A lady lost her handbag at the mall.  An honest young lad found it and returned it to her.

Looking in her purse, she said, "Hmm, that's funny.  When I lost my bag, there was a $20 bill in it.  Now there are twenty $1 bills."

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