Ross: Oh, my God. She thinks we're engaged! Why? Why, why would she think we're engaged?
Phoebe: Perhaps because you gave her an engagement ring? You know, Ross, doctors are supposed to be smart.
Ross: I didn't give her that ring.
Phoebe: You didn't?
Ross: No!
Phoebe: So whose ring is it?
Ross: It's mine.
Phoebe: Is it an engagement ring?
Ross: Yes.
Phoebe: But you didn't give it to her?
Ross: No.
Phoebe: But you were going to propose?
Ross: No!
Phoebe: I might be losing interest in this.
