Quote from Monica in The One Where the Stripper Cries
Ross: Did you know Chandler kissed Rachel? Monica: What? When was this? Ross: 1987. The weekend you guys visited me at school. Monica: Oh, my God. That's wild. Chandler: Yeah. But it was, like, a million years ago, so it doesn't matter. Ross: Yeah, but it matters to me. Chandler: Why? Ross: Because the night you kissed Rachel was the night I kissed Rachel for the very first time. Chandler: You kissed her that night too? Monica: Two guys in one night? Oh, I thought she became a slut after she got her nose fixed.
