Season 2: Episode 25: The One With Ross' New Girlfriend
Ross comes back from China with his new girlfriend, Julie, and Rachel has a really hard time dealing with it. She winds up sleeping with Paolo and hates herself for it. Joey persuades her to tell Ross how she feels, but when Ross tells her how in love he is with Julie, she can't bring herself to do it. Meanwhile, Phoebe has done such a great job cutting Chandler and Joey's hair that Monica begs her to cut hers. Phoebe is hesitant at first (because of Monica's "control" thing) but finally concedes; then gets confused and gives Monica a Dudley Moore haircut instead of the Demi Moore cut she requested. And Chandler goes to Joey's tailor for some alterations and gets "fondled;" it dawns on Joey he's been "fondled" by his tailor all these years.
