Shouted over the PA, we hear directions given to these muscle-bound freaks of nature. The director says things like, "Howl for me, Wolf," and "More posing, Justice" and my personal favorite - "Look menacingly while you stare at your balls" (he was referring to the giant balls that were swinging from the rafters, I hope).
Hey, there's only one more "30 Rock." There ain't much more else on. Though we really wish Olbermann would show up at the midway point and tell us whom we should hate. We need signposts.
My Brain Says Rage has some info on this as well.
