I liked how they re-ran the Aids Walk episode and the episode where Kramer was supposed to watch Elaine's armoire (sp). I didn't realize until I saw them both for the second time that the guys that stole the armoire and the guys who beat up Kramer for not wearing the Aids ribbon were the same people. I know this is not really an example of what you were talking about, because I think both episodes were from this season. Thought I'd mention it anyway!
