There was one story about people shoveling the snow for a parking space in front their house. This apparently is a problem for the Chicago police every winter. What happens is that somebody will park in a nearby parking lot, then slave away for how ever many hours it takes to shovel out a car-sized space in front of his house, naturally so he can park his car there. Then he goes back to the lot to get his car.
When he returns home, he finds that the space has been taken by some _other_ car. He is, well, upset.
What most people do is write nasty notes etc. and place them on the windshield of the offending vehicle. Where the police get involved, however, is the occasional case where the individual vents his wrath in somewhat more violent means. Tires and throats have been slashed over this.
One time a fellow got creative. Instead of doing the usual nasty, he got out his garden hose and watered the automobile down, really well. I mean, very, very thoroughly. The water, of course, froze solid. When the owner returned, instead of a car, he found a car-sized popsicle.
The note on the car read: "You want the space? Here, it's yours until spring!"
