Actually, I didn't do this either. Really, truthfully. None of my farm friends did this. To us, it was a "city thing" that farm kids didn't do.
However, I still remember the After Party my high school class had after our graduation. We all met at one of our Cheer Leaders homes. Don't know where her parents had gone after graduation, but not home. Anyway, the parking area at the house was fairly big and some of us guys were told that the Class President, and his girlfriend would be one of the first there. So, most of us guys got to the house at the same time, knew the color/model of the Class President's car, and parked our cars in a half circle facing it. During the party, the President and his girlfriend excused themselves and left. All the guys knew where they were going...…..to his car to "neck". We all waited a few minutes, then, very, very quietly sneaked out to our cars, very quietly opened the drivers door, got in and turned our headlights on to the Presidents car. Both, the President and his girlfriend were shocked and all us guys could do was laugh our butts off. To this day, we all remember this.
