The One With the Sharks - S9-E4
Corrected entry: Phoebe and Ross talk about how Phoebe's never been in a serious relationship before. In season five she dated Gary for some time and they moved in together. When she later moves in with Mike she says she's always wanted to live with a guy but she has.
Correction: Phoebe says three times that she's never been in a *long term* relationship. She doesn't say that she's never been in a *serious* relationship. The relationship with Gary wasn't long term and she only lived with him for one night because he shot a bird the next morning--hardly what we could call living with someone and something she would want to forget.
