ok the main problem that stemmed into all him problems i see is that he practiced no where near enough to do this on the last one, so he put himself in a large ammount of danger which shouldnt have been done, and then the biggest problem that i would like th smack this guy across the head for is the fact that he took a potentially dangerous trick where you could seriously hurt yourself if you messed up, and then didnt practice it, and then brought up a spectator, and put the spectator in danger, and what happend? the spectator got hurt, if theres the remote chance that you can pick the wrong one and end up stabbing yourself, do it yourself, dont have a spectator slam their hand down on it for you! its like handing an exacto knife to a child, theres a large chance some1s gonna get hurt, and as such, you shouldn't do it
