Quote from Rachel in The One with Rachel's Inadvertent Kiss
Rachel: Oh, my God. I can't believe it. I got a second interview. Joey: I bet that kiss isn't looking like such a mistake now, is it? Rachel: Wait a minute. You don't think that's why he wants me back? Joey: Yeah! ... No? Monica: Kiss? What are you talking about? Rachel: I accidentally kissed him in the interview and now he wants me back, of course, because "Let's bring back the girl who kisses everybody!"
