Lol, yeah dude, I showed a kid something similar, except we told him to stand in one spot and spin twice, and shoot a dot on the wall... Took him about ten minutes of killing me to realize I had my handicap on, becuase I spawned infront of him and he seen my sheilds drop. That was about a year ago.
Funny thing is is 2 days ago I met a kid that swore up and down it would work, even after showing him I had to turn my handicap on for it to really work... Hes like, I can take 4 shots to the head with a sniper to die... I was like wow dude... he said hes used it in a matchmaking game too! Kid was a complete retard, but he said he had been playing for more then 6 months!
