Quote from Phoebe in The One Where Phoebe Runs
Phoebe: Me, I'm more free, you know? I run like I did when I was a kid, because that's the only way it's fun, you know? I mean, didn't you ever run so fast you thought your legs were going to fall off? You know, like when you were running towards the swings or running away from Satan? The neighbor's dog.
