The best prank I ever pulled was when I convinced my nephew his sisters and I filed a missing person report after he took off with his brothers in the car to take a cruise around this unfamiliar town. I had his sisters in the car and was in charge of all five kids. The oldest one had his license and thought it would be funny to leave when I returned home with the girls. I followed my nephew for awhile and then took the girls to see a friend. Of course when we were no longer following them they returned home and gave us the third degree about where we were. It was then I told my nephew we went to file a missing person report at the police station. Poor kid was sweating bullets for an hour or so. He believed I did file a report and I doubt he ever tried a trick like that again.
