Phoebe : You know how John Lennon was better than the rest of the Beatles, but didn't realize it until he met Yoko Ono? Well, I'm Jack's Yoko.
Liz Lemon : You want to be Yoko?
Phoebe : This is none of your business, anyway. I'm marrying Jack. He's everything I ever wanted.
Liz Lemon : Oh, I bet he is.
Phoebe : [in American accent] You don't know anything about me, so back off!
Liz Lemon : What happened to your accent?
Phoebe : [back to British accent] Um, I don't know what you're on about. You daft wanker!
