Every year at Halloween, I set one of those "Take One Only" baskets outside of my house. I hide a few meters away in some bushes with a blowgun and a pile of dull, metal, stun-darts. For every greedy fuck who takes more than one, I take a shot or two at them, usually aiming for exposed skin (where dull darts hurt the most). If the parents are with them, I use a sharp darts on them because they didn't set any good morals for their kids. Seriously, there are so many of these amoral kids that I end up running out of darts and having to go back inside for more.
Well, it's great fun and good practice for your aim. Try with a bb-gun, air-soft gun, or maybe a real gun if you don't have any problem with killing people.
Happy Halloween, ebaums.
