Quote from Phoebe in The One After Vegas
Monica: This is insane. Phoebe: What's the big deal? You know, it's not like it's a real marriage. Chandler: What? Phoebe: Yeah, if you get married in Vegas, you're only married in Vegas. Monica: What are you talking about? If you get married in Vegas, you're married everywhere. Phoebe: Really? Monica: Yeah. Phoebe: Oh, my God! Oh, well.
