One of the great joys of living in a free and prosperous society: you get to do stuff with no practical value whatsoever. You get to have fun. In really free societies you get to that with stuff that goes BANG. And pointy stuff. Not to mention rubber bands. Put it all together and . . . move over lawn darts! And here he is: the rubber band man, firing knives from underneath the barrel of an M16. How great is that? As they say in these parts, wikkid pissa.
