Now THIS is a funny site. http://www.rottenneighbor.com/
People post text, photos and videos of their IDIOT Neighbors in action. You can even type in your address and see if anyone has complained about you or someone on your street! Apparently I have two within 1k of me. A post about someone being "deafeningly loud" and an "Enemy of marriage and family" (that is to say, someone who sleeps with already married people).
Check out this meatball with the ATV below. If you go to the site it shows you a google map of the area with the location of the rotten neighbor marked. Pretty funny!
