Phoebe: No, no, that you and Rachel are engaged.
Ross: What?
Phoebe: Oh, it's a secret? Oh, goody. Yes. Ooh, we haven't done the secret thing in a long time.
Ross: Phoebe, there is no secret, okay? I didn't propose.
Phoebe: Are you lying? Is this like that time you tried to convince us you were a doctor?
Ross: I am a doctor.
