Stress relief balls can suck my nuts.
Anyway, I highly suggest that you buy this game if you know a lot of annoying people. Just skin or imagine their faces on the people in this game and shoot away. Just don't take it into real life, that would be bad. :)
The people's reactions in the game are priceless. If you bump into someone, they call you an idiot. If you dress up as a cop and start shooting people, the cops say, "Hey, cut it out, it's bad for business." It's a great game for anyone to screw around in.
Buy it. Now.
