I'm confused. Is she married or just registered to be married?

Hey..it's Vegas...they're not married for real!


.....

Phoebe: What’s the big deal, y’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! ... Eh! Well…

Couldn't resist....
