I think the problem with this question (and the reason why it has gone unanswered for two days) is it is too esoteric. Since each Seinfeld episode usually has 4 distinct plotlines, 1 for each character (though they may intersect), it is quite difficult to keep them together. Where it is easy to remember the Elaine plot from episode x, the Jerry plot from episode x, and Kramer plot from episode x, and the George plot from episode x, each by themselves, it is much more difficult to remember that they were all from episode x. I can't specifically remember the George plot from many episodes, just as I can't remember the Jerry plot, Elaine plot, or Kramer plot. I guess what I'm saying is, "I have no frickin' clue!"
