Unless there is some serious info we don't know, it really seems like a pretty harmless gag. I know, I know, once I flipped out when some guys in my house wrapped my car in paper towels. They don't realize how much we care for cars. That being said, the paper didn't hurt anything on my car, and later on I felt bad about flipping out. Now, if they had keyed the car or poured OJ on it or did something which would cause damage, I'd get it. This is probably somebody who likes your daughter, or maybe one of her jealous friends who doesn't have a car (or a car as cool)
