Super Granny

An elderly Florida lady did her shopping and, upon returning to her car, found four males in the act of leaving with her vehicle.  She dropped her shopping bags and drew her handgun, proceeding to scream at them at the top of her lungs, "I have a gun and I know how use it!  Get out of the car, you scumbags!"

The four men didn't wait for a second invitation, but got out and ran like mad, whereupon the lady, somewhat shaken, proceeded to load her shopping bags into the back of the car and get into the driver's seat.  She was so shaken that she could not get her key into the ignition.  After having tried and tried, and then it dawned on her why.   A few minutes later she found her own car parked four or five spaces away.  She loaded her bags into her car and drove to the police station.  

The sergeant to whom she told the story nearly tore himself in two with laughter and pointed to the other end of the counter, where four pale white males were reporting a car jacking by a mad elderly woman described as white, less than 5' tall, glasses, and curly white hair carrying a large handgun.

No charges were filed.
