do it in a fight, that's all I got to say. If you can do that, and it works.......fine. But like I said, training for a combat situation is ALOT different than actually BEING in a combat situation. Reaching for a vulcan nostril hold or a shiatsu cock tip incapacitator while in the midst of an all out brawl is bordering on retardation and you deserve the consequences. I'd like to see your brother try that shit on a 350 pound tongan.....it just don't work. Maybe if you sneak up behind him and pull some splinter cell shit, fine. But against someone who knows how to fight, you're gonna take massive meaty paws to the face as you're reaching for that wet willy or purple nurple. Sure the shit hurts when you're in class.........and I bet you even think to yourself how quickly you'd tap if that was done to you in a real fight. But in a real fight, if the hold doesn't somehow disable your CNS, chances are you're not gonna feel it. If it can be done, I wanna see video proof of it.
