So, I caught that when it was first posted, and I still don't get it. That's just someone taping two kids as they play Doom 3? Or what?
And with that... Who, when playing a video game, screams? What kind of sissy would do that?
BTW I nominate Durge/Greg(g) or Peep Admiral/Darth Cyrax (A GH member, but worthy of the nod) as the culprits. Or any mix of the above.

I could think of a couple ninny's from some other site's though *cough*lurking dorks*cough*
