Quote from Monica in The One with Ross's Denial
Monica: Hey, when you move in, Rachel's room will be empty. Do you want to talk about what to do with it? Chandler: Sure. Monica: I was thinking we should have a beautiful guest room with a mahogany sleigh bed and bedside tables with flowers on it all the time. And then we could have a roll-top desk with little comment cards so people can tell us how much they love staying here. Or whatever. You know, I really haven't thought about it that much.
