Quote from Ross in The One with Rachel's Book
Ross: Look, this is my home, and I want to be able to come and go whenever I want. Phoebe: Okay. I will find someplace else to do the rest of my appointments. I just don't know what the big deal is. Ross: The big deal is I don't want naked, greasy strangers in my apartment when I want to kick back with a puzzle- Beer, cold beer.
