Quote from Ross in The One with the Jam
Chandler: Do I look fat? Both: No. Chandler: Okay. I accept that. When Janice asked me and I said no, she took that to mean I was calling her a cow. Rachel: Okay, walk us through it, honey. Walk us through it. Chandler: Okay. Janice said, "Hi. Do I look fat today?" And I looked at her- Ross: Whoa, whoa, whoa. You looked at her? You never look. You just answer. It's like a reflex. "Do I look fat?" "No." "Is she prettier than I am?" "No." "Does size matter?" Rachel: "No." Ross: And it works both ways.
