Besides the Tonya Harding/aspiring understudy bit and the Johnny Cochrane/Jackie Childs thang, current affairs are often replayed in the show's context as a shadow of the real events, and are often some of the most clever set pieces on the program. I'm not talking about the Dinkins/Giuliani yogurt episode (since that involved the actual candidates and was not, as far as I know, based on anything real.)
Using your sharp powers of analogy (now don't get fuzzy on me), who can think of any other instances of current events "revisited" by Seinfeld and company? Mr. Pitt and the Poland Spring bit doesn't count, since I don't consider Hitler in 1939 "current".
