I have a gun and I know how to use it!

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 drew her handgun, proceeding to scream
at the top of her lungs, "I have a gun, and I know how to use it!
Get out of the car!" The four men didn't wait for a second threat.
They got out and ran like mad.

The lady, somewhat shaken, then proceeded to load her shopping bags
into the back of the car and got into the driver's seat. She was so
shaken that she could not get her key into the ignition. She tried and
tried, and then she realized why, .. it was for the same reason she
had wondered why there was a football, a Frisbee and two 12 packs of
beer in the front seat.

A few minutes later, she found her own car parked four or five spaces
farther down. She loaded her bags into the car and drove to the police
station to report her mistake. The sergeant to whom she told the story
couldn't stop laughing. He pointed to the other end of the counter, where
four pale men were reporting a car jacking by a mad, elderly woman
described as white, less than five feet tall, glasses, curly white hair,
and carrying a large handgun.

No charges were filed.
