Hello, long time lurker, first time poster. I have a question about an episode. I am a huge fan of the show, I have the entire series on my DVR and own all the discs. I know I have seen every episode at least thirty or forty times. When watching a clip I can usually tell what show it is in just a few seconds, but I am having trouble identifying one. In the video below, the first ten seconds or so show the boys at some kind of dance studio dancing with some older women (you'll have to play the video, it is not the screen shot that is showing). For the life of me I cannot remember ever seeing this particular clip. It seems to be from one of the earlier seasons. Can someone please tell me what episode this was in?
