Oh I don't know how it works. ...I just thought it was cool. But then I heard from some of our nation's highest ranking official and should be roll models like Nancy Pelosi that I shouldn't own this, and not only should I not own it I shouldn't even be allowed to. I was told stories by these people how these types of items just break out of gun safes rob liquor stores, knock up teenagers, and make going to the grocery store unsafe. So I thought I should destroy it but then I remembered people like Pelosi or Boxer or whomever they saw fit could have such items. So I turned sheep and have placed it up for sale so someone like Pelosi or maybe even Barack O himself could obtain it to make us all safer.
