I had my truck's 3 tires slashed at a public school parking lot. I got revenge by using a jack and flipped his truck upside down before the classes were over...he was very surprised that it was upside down...ruining his cab. Cops got involved and we both got cleared cause it was even.
My camera, cash, and wife's purse was stolen few months ago at my mother's house when it was parked overnight. Unfortunately it was unlocked. Ever since, we learned the habit of keeping the car locked.
Of course, I had many things stolen.. fishing poles, tackle box, hunting rifle, 15 wooden baseball bats (at tournment in AZ), Baggage (at Little Rock airport), and few other small things.
