Another good one that I know of . A friend of mine is a contractor . One night late he was on the job site well after dark . He watched someone drop off a bunch of crap next to the onsite dumpster . Instead of saying anything on the spot he followed them after they left to find out where they lived . The next day he had his guys load all the stuff they had dropped off plus a full dumptruck load of crap into his truck . Then about 2 AM he went and dumped it back on their front lawn . I would have loved to have been there in the morning when these jerks saw that
