Remember: Stay In The Lines.
Bad parking jobs can get really obnoxious, especially when you're trying to find somewhere to fit in an already pretty packed lot. It seems like this person not only got a little peeved, but found a pretty turtley way to give this driver an education.
Have you guys ever left a note to a bad driver? Have you ever received one?
I've had it happen to my friends before, but the only times I've ever received a note on my windshield was when someone accidentally dented my parked car. (Fortunately, it wasn't THAT bad.)
