Last night the show stretched itself. After being on for 8 years no one can accuse it of playing safe. This should be taken into account by those who wish to make critical comments about the show. I myself, am one of those who wish to make a few quibbles.
One triumpth of the endless flashback mode was that it allowed a nonghostly Susan to make a return appearence on the show. And apart from the creative gimmick of the endless flashback was the return of the "Braless Wonder." For this we should be thankful.
Also, the flashback mode allowed us to see the first meeting of Jerry & Kramer, an event that a more conventional episode wouldn't have allowed or needed. The surreal aspect was the fact that on least two occasians the humor not only survived but was enhanced by having the punchline precede the joke.
Parts of it lacked credibility, for example the idea that the "Braless Wonder" would have Elaine as a maid of honor or that she would break of the marrige when she found out that in a previous incarnation (Before the Hindu meet her) Elaine had sleep with the groom. Did the "Braless Wonder" think she was marrying a virgin? One last item on the debit side: By flashing back it papers over missing parts. However, this might by some be considered the proof of the genius of the show. After all very few people are going to deconstruct the episode on their computer (or their minds) and reassemble the show front to back in order to find the missing pieces,
This in my not so humble opinion trumps the "Bizzaro Jerry" episode for surreal humor.
