Quote from Chandler in The One with Ross's Sandwich
Phoebe: Okay, look. You want to hold onto your food? You gotta scare people off. I learned that living on the street. Ross: Really? So what would you say, Phoebe? Stuff like: "Keep your mitts off my grub." Chandler: Say, Ross, when you picture Phoebe living on the street, is she surrounded by the entire cast of Annie?
