Friends: The Best Episode From Every Season
6. Season Five: The One Where Everybody Finds Out
After spending the best part of a season trying to keep their relationship secret from the rest of the gang, season five's The One where Everybody Finds Out forces Monica and Chandler to confront the possibility that their friends already know about it.
Forcing Rachel, Phoebe and a reluctant Joey into a battle of wills with the happy couple, the episode switches Monica and Chandler's relationship from a funny fling to a genuinely lovely romance, but makes each character - and the audience - work for their declarations of love in the best way possible.
Mostly played for laughs but ending with a beautiful twist, The One where Everybody Finds Out would change the show forever moving forward, and achieves it flawlessly with an episode of endless quotability and effortless cast chemistry.
