Phoebe turns out to be married to Duncan, a gay friend who needed a green card. Phoebe did love him, and finds those feelings returning. Now (six years later) he’s back and needs a divorce. Turns out he’s not gay, and is getting married to someone else. The revelation of Phoebe’s secret marriage prompts several other discoveries: The underwear on the telephone pole outside is Monica’s, from when she had sex with Fun Bobby on the terrace; Chandler has a third nipple; Joey was in a porn movie (which they then watch). Ross is nervous about the prospect of having sex for the first time with Julie. He approaches Rachel for advice; her own interest in Ross keeps her from being completely honest, and she tries her best to see that it doesn’t happen.
