Rules here to stay

Well, folks are the "rules" here to stay ?   And if so, could U live
w/ them ?  Seemed to be o.k. w/ Jerry and Ellan, when mentioning "this
that and the other".   Ending tonites episode w/ Kramer's line " I
really like the two of you when you weren't a couple" was a xcellent
why to close the show.
