So no one told you life was gonna be this way. Your job's a joke, you're broke, and instead of a love life you spend all of your spare time watching repeats of Friends on Comedy Central/Netflix/DVD etc (although let's be honest, obviously the best relationship is the one where you spend all of your time together watching the show).
It has just gone 21 years since Friends started, and over 11 years since it ended, with - *spoiler alert* - Rachel getting off the plane, Chandler and Monica saying goodbye to Apartment 20, and the gang heading off for a cup of coffee ("where?"). However, thanks to how much it has remained on our screens, in our hearts, and a part of pop-culture, it's like it's never really been away (they'll be there for you, after all).
It's taken on a new life thanks to the rise of the internet, which the show was a little to early to really capitalise on first time around (save for Ross being dead), and a part of that is the number of theories about the show that have sprung up since it ended.
Like most fan theories they need to be taken with a pinch of salt, or a whole shaker of the stuff, yet at the same time will leave you thinking they could be true. As Joey tells us, there's a lot of theories that didn't pan out, and these are the ones about Friends that you need to hear.
