Of course it was great, because it was the episode with Rebecca McFarland (my query about whom has not drawn any responses, unfortunately).
Having seen it a couple of times, I really think that the "moves" Elaine uses were copied from an analysis of someone undergoing a certain type of seizure. If that were true it would be harsh but it wouldn't unusual for the show. One thing I like about the show is that EVERYTHING is fair game for humor.
