Quote from Phoebe in The One Where Ross Is Fine
Phoebe: But I can move some stuff around and I'll be there. You and Alice just take the whole day together. Frank Jr.: You'd do that for us? Phoebe: Are you kidding? That's what sisters are for. Frank Jr.: Oh, look at them. I love you so much. Oh, crap, don't wake up! Don't wake up!
