Quote from Barney in Columns
[flashback to Barney and Lily at MacLaren's:] Barney: A nude Barney is a challenge. But I think you're talented enough to immortalize this. Now is the time. I'm 31. I'm at the peak of my physical beauty. If I were a woman, I'd have passed it long, long ago. Long ago. Lily: Forget it. I promised Marshall he was the only guy I would ever see naked. Barney: I'll give you $5,000. [back to Lily and Marshall in bed:] Marshall: We're going to Loch Ness! Lily: Yeah!
