Actually, this kid is acting it all and is doing it for two reasons. 1. Get a lot of attention on the net. (Mission accomplished) 2. Think up even weirder things for future videos. As far as I'm told, the guy is actually a normal person with an awkard sense of humour. I seem to be in IRC channels where this crap is constantly posted. In that UT video he's at first cursing it for it taking too long to load, then he's cursing that it loads at all because he doesn't want to load it - he wants to play it, then he screams mindlessy until he finally destroys his keyboard. I guess it was either broken from the start or he just doesn't care and had a replacement ready.
