It seemed to be some kind of reality show like 'Big Brother' The clip was about this one guy who got voted out and had to leave. Before he left he said something like "This is for you" and then began screaming like a possessed Monkey ("NGAH NAGH NAGH") while flexing. The people watching him looked on completely straight-faced until he finished and left.
