Phoebe: So, how was your day? Frank: Oh, well just probably the worst one since I've been alive. Phoebe: What, mm, what happened? Frank: Um, Alice, ah, she, ah, called it off. Phoebe: Oh no. Did, um, did she say why? Frank: Uh, no, not really, just that I was too young, you know. But I don't see how I could all of the sudden be too young, 'cause I'm older than I was when we first got together.
