Quote from Phoebe in The One with Phoebe's Husband
Duncan: I kind of need a divorce. Phoebe: Oh ... 'kay. How come? Duncan: Actually, I'm getting married again. Phoebe: What? Duncan: Oh, God, I don't know how to tell you this. I'm straight. Phoebe: [gasps] I don't understand. How can you be straight? You're so smart and funny and you throw such great Academy Award parties!
