You can pretty much quote it word for word, know every bit of trivia and probably own a mug or set of pyjamas with the logo on it - and you'll never stop watching it.

Friends will be rerun on telly until the end of time and we're not complaining because honestly, what else would you watch when you're hungover? Plenty of fan theories have circulated online about the show since it ended and the latest one is kind of bumming us out, if we're honest. Some Friends fans reckon that Chandler was still mad about Kathy when he married Monica. Chandler and Kathy dated in season four after she first went out with Joey. They broke up when Kathy slept with someone else after a fight but Chandler may never have stopped loving her, according to this theory. Remember when Chandler wore the pink rabbit costume to the Halloween party in season eight? Monica had gotten it for him, saying she knew his favourite kids' book was 'The Velveteen Rabbit'. You might recall that Chandler had bought that book for Kathy's birthday back in the day, knowing she loved it, but never mentioned that it was also his favourite. "Chandler held a torch for Kathy for all those years and it was so strong he adopted her favourite childhood book as his own," the Reddit who came up with the theory surmised. It is odd that 'The Velveteen Rabbit' came up twice like that in the show but we reckon that this theory is BS. We need to believe that this was a coincidence because honestly, Monica and Chandler's love was so sweet that we can't bear the thought that he was into someone else all along.
