I've been lurking around here for awhile, but never posted anything. And I have some damn good ideas on how to keep the show going for AT LEAST one more season.
1) LIVING ARRANGEMENTS. Yeah, Chandler and Monica are getting married (zzz...). That doesn't mean that they have to live together UNTIL the wedding. What if Joey, being Joey, decided to move out of his apartment because "he's a big star," leaving Rachel stranded? Then she could move in with an eager Ross (maybe pick up the fact that he re-loves her that the writers dropped like a hot potato). C&M decide, for their own benefit, not to live together. So Phoebe and Monica move across the hall into Joey's. And Joey realizes he has nowhere to go when he can't afford a big apartment, so he lives with Chandler. For a half season, we have Joey/Chandler interaction, Phoebe/Monica arguing, and Ross/Rachel action. And when Chandler and Monica get married, why not let Joey stay with them because he doesn't wanna live with Phoebe?
2) ROSS AND RACHEL. Get them back together. As much life as Chandler and Monica put into the show during season five, they've taken out twice that amount. It's time to bring Ross and Rachel back; they will pull in sensational ratings. It's easier to do it while they live together, as well.
3) GIVE PHOEBE/JOEY DIRECTION. Joey has a part on a TV show. What if the show was a hit and a soundtrack was in the works? Since the producers of the CD want no-names, he recruits Phoebe. This, inadvertantly, gives her amazing direction, once her song is the first single from the album and goes to number one.
4) GUEST STARS. Introduce the Gellers to the Bings! How about Mr. Bing is played by two people--Nathan Lane and RuPaul?! Bring Kip on, as a guest at C&M's wedding!
5) TWISTS. Phoebe asks Kip to live with her (he's divorced now). C&M go to Hawaii for their honeymoon. Joey finds out that he's shooting on location down there, so he invites his friends to join him. What if Ross and Rachel accidentally got involved in a Polynesian wedding ceremony? Would they tell their friends that they've gotten married TWICE--neither time knowing what they were doing?
6) GROWTH. What if Chandler and Monica move? Into a house? How about if Phoebe became successful? What might happen if Joey got a REALLY big break? How would Ross handle Rachel's pregnancy?
The show has lots of life left in it...all the writers need to do is write about it!
