Series 3, Episode 13
Monica and Richard hook up again after meeting in the video shop but agree to be 'just friends' despite obviously still having feelings for each other. Phoebe introduces her new boyfriend and his obliviously hanging member to the guys in the coffee shop. Rachel is given The Shining to read in exchange for offering Joey a chance to read Little Women.
My favourite part of the episode is when the audience realise Richard is the one speaking to Monica in the video store - you actually hear them gasp with delight.
