Season 10: Episode 218: The One Where Ross Is Fine
Ross is clearly freaked out by Rachel and Joey's relationship, but keeps insisting he's fine. He arranges for Rachel and Joey to have dinner with Charlie and him, where he's an emotional wreck and very drunk. Chandler and Monica, frustrated by the complexity of adoption, visit Phoebe's friends (Bill and Colleen) who have an adopted son (Owen). Chandler mistakenly reveals to the boy that he's adopted. Phoebe gets a visit from Frank Jr. and the triplets. Frank is totally overwhelmed by the responsibilities of fatherhood, having not slept in four years. He asks Phoebe to take one of the kids, but then realizes he could never give up any of them.
