I really loved the episode that featured the dancing troupe, "The Lockers". They were, in my eyes, the ones that broke the door down for break dancing. The way the Lockers danced was amazing. I really enjoyed people who danced like that. So when break dancing started in the 80's, I kinda laughed because I knew where it came from. Fred Berry was a member of this dance troupe. I put a link here which talks about the beginning of this group as well as the dance style in general. Take a look:
