Season 2: Episode 31: The One Where Ross Finds Out
Ross and Julie announce they are getting a cat -- together. That night, Rachel gets drunk on a date and all she talks about is Ross. She decides to get "closure" by calling him and telling his machine she is "over him." This is how he finds out she isn't over him, and he is now faced with the agonizing task of having to choose between her and Julie. Meanwhile, Chandler has put on some weight so the currently unemployed Monica helps him work out -- every single day. And Phoebe's irked because the guy she's been dating won't sleep with her.
