I can't understand that kind of vandalism either. I will admit that I did a lot of stupid stuff in high school. I still do actually. But everything we did and do has an element of humor to it. Like placing the lighted reindeer in people put in their yard at christmas into sex positions. Its funny. But simply destroying or defacing things, thats just lame.
Here is my favorite: Here is my favorite sign. But first a little background. On more than one occaison, my friends and I attempted to eat at Steak and Shake but were refused service because only 2 of the 4 of us were actually going to order something, the other guys were not hungry and simply wanted water. This is at like 10-11pm and there are literally 2 tables occupied at the whole restaurant. They have the policy because people used to go in there and hang out forever and never order any food, but I thought refusing 2 of 4 paying customers when the restaurant is basically empty was asinine. That was two summers ago...we made sure that the employees had a lot of extra work to do that summer. They had an advertisement on their sign for "New Bits & Pieces". We made sure that they had to change that sign back at least once a week for almost the entire summer, sometimes striking multiple times a night...we were never caught.
