If you ask us, humans kind of got the short end of the evolutionary stick. I mean, we really suck. We can't live underwater, spray stink juice, or move stuff with our minds or anything. We do, however, have the uncanny ability to be really ballsy when it comes to trying every stupid idea that comes into our heads; like strapping on an old pair of MC Hammer pants and jumping off the nearest mountain in order to harness the miracle of flight. These guys take Jackass to a new level.
