THat's hilarious! One day, my coworker's teenage daughter had mom's car. After running an errand to Target with a girlfriend, she stopped at the local mall. She had failed to lock the car. When they returned to the car, boys who knew them and the car had gone into the car, opened the Target bag, found a box of pads and one of pantiliners, took them out... and stuck them all over the exterior of the car.

It's funny NOW, but that stuff is mortifying when you're only 16! :)
