Billy drove his brand new Mercedes to his favorite sporting goods store. He parked it outside and went in. Betty, a pretty blonde saleswoman who always served him, greeted him and asked if she could help. Billy said thank you and told her that he would just like to look around on his own today.

Five minutes later, Betty came running up to him yelling, "Billy! Billy! I just saw someone driving off with your new Mercedes!"

"Dear God! Did you try to stop him?," Billy said.

"No," she said, "I did better than that! I got the license plate number!"
