Because I'm bored :-)
Kathy cheating on Chandler was pretty unbelievable. They sacrificed a lot to be together and were very much in the honeymoon phase. Matthew Perry and Paget Brewster actually went to the producers to protest this and asked that instead she reluctantly leaves him to pursue a career elsewhere but they said no.
Joey was the only one who we never see get drunk throughout the whole show.
Ellen DeGeneres was apparently first choice for Phoebe but she turned it down.
Reese Witherspoon never got a cheer when she made her cameo as Rachel's sister... why? She was already pretty famous by that point.
I think we can all agree Brad Pitt's cameo cheer was the loudest! Closely followed by Christina Applegate.
Some of the scenarios were pretty unrealistic. Being divorced 3 times would be seriously upsetting in real life and not something your friends would regularly take the piss out of. Same with being bullied for being fat.
I think Rachel is the Friend who developed / changed the most. She started off as a whining, spoilt brat and ended up as an independent, considerate woman. Probably followed by either Ross from needy to cool or Chandler from being commitment phobic to a family man. I don't think Monica, Joey or Phoebe evolved very much at all. Thoughts?
Chandler and Monica in real life would be a very annoying couple. Both very full on. Janine had it sussed!
Phoebe and Joey would NEVER have been able to afford to live in Manhattan.
Ross and Rachel broke up and within a couple of months Rachel could hear him having sex with Bonnie in the next room at the beach house. In real life this would be absolutely traumatising.
Couldn't stand Emily or Susan and for some reason I feel pretty meh towards Mike. I much preferred David The Science Guy. He was so dryly funny.
Pete took Monica to Italy (or was it France?) for their first date. Even with millions of dollars how was this possible in a few hours?
Janice was perceived to be annoying. But actually other than the awful laugh and a complete inability to read the room... she was bloody lovely and a very good person to have as a friend. She gave good advice and I really liked her.
If Phoebe's brother Frank had been more mature and cut his hair he would have been really fit!
I'll probably think of others. For the record I LOVE the show I just like talking about it to other fans :-)
