I would love to see a Seinfeld reunion, possibly on the 10th anniversary of the final episode (or maybe sooner than that).
How about Jerry finally getting married and being a family man? Or George, like Jerry, also moving to LA and serving as one of the writers for the Larry David Show?
How about Elaine would finally getting work at Double Day (maybe she discovered some interesting subject matters while in prison)?
And Kramer could get that make-over from the Queer Eye for the Straight Guy folks (imagine the Fab 5's expression upon seeing Cosmos' apartment equipped with the hot tub and the talk show set)?
