They really seemed to get into it: sound effects, "stunts", even some spitting. They even did some moves where "The Force" was their weapon. There were six of "them", and, at one point, they even lined up in formation and went through a series of moves. From what I could tell, some of the one-on-one "fights" were based on particular fights from the "Star Wars" movies - complete with bits of dialog.
It was quite fascinating and entertaining, and by the time I finished watching them, it was about 2:00am... And by the time I got home... Sleep.
