For the 1/08 episode: I got the biggest kick out of Elaine imitating Puddy's look & stare. That was great!
On the subject of spinoffs - why just focus on one of the characters getting their own show?
I think the show could go on with all of the remaining characters if Jerry left. Sure, there would be a void (and an obvious need to change the title) but hell - just have Jerry taking off somewhere to find himself or something - perhaps a few 'guest' shots during the season - and voila! The rest of the cast could carry on for a couple of more seasons.
Seinfeld has a huge cast of regulars and semi-regulars that can be brought in and out every other episodes now - and if more are introduced ...?!? The story lines (or 'nothingness') can continue as long as the writing is there.
I say it can be done!
