Quote from Lily in The Platinum Rule
Lily: And it's so convenient. They're right across the hall. Say it's Sunday and we want to have a brunch double date with someone. Marshall: We just go across the hall. Lily: And say we want to have a dinner party exploring the wine and cuisine of France's Loire Valley. Marshall: We just go across the hall. Lily: Say we want to play a game of charades... [Marshall mimes] Barney: You just go across the hall? [Marshall agrees] Lily: Come on people, get excited for us! We've got a great thing going here. Barney: That's what I thought.
