Joey tries to tell Rachel that he didn't really propose, but can't get a moment alone with her. Phoebe gets involved but that just confuses things. Joey tries to keep Ross away from Rachel until he can straighten it out. Monica and Chandler continue trying to get pregnant; Mr. Geller discovers them having sex in the janitor's closet and is mortified, until he learns that they're trying to conceive; then he's so enthusiastic he starts giving them advice, and Monica is mortified. Joey, Ross, and Rachel finally straighten out that no one was going to propose; Ross was just planning to ask Rachel if they could start up their relationship again. Everything is just about smoothed out when Ross realizes that Rachel is wearing the ring, and therefore must have said yes to Joey.
Phoebe: She said you actually proposed to her.
Ross: Well, I didn't! I didn't propose! Unless.... Did I? I haven't slept in 40 hours, and it does sound like something I would do.
Rachel: You were going to propose to me?
Ross: Uh, no!
Joey: Well, this is awkard.
Ross: But I was going to see if, you know, maybe you wanted to start dating again, but that was all, Rach.
Joey: Dude, step up! I proposed!
Ross: No you didn't!
Joey: Oh, that's right. There's a lot going on here.
