"An elderly lady did her" joke

An elderly lady did her shopping and upon returning to her car found four
males sitting in the car.
She dropped her shopping bags and drew her handgun, proceeding to scream at
them at the top of her voice that she knows how to use it and that she will
if required...so get out of the car!
The four men didn't wait around for a second invitation but got out and ran
like mad, where upon the lady proceeded to load her shopping bags into the
back of the car and got into the driver's seat.
Small problem: her key wouldn't fit the ignition. Her car was identical and
parked four or five spaces further down.
She reloaded her bags into her car and drove to the police station. The
sergeant that she told the story to nearly tore himself in two with
laughter and pointed to the other end of the counter where four very pale
males were reporting a car jacking by a mad elderly woman.
No charges were filed.
