Barney: It's a sad day in New York, Ted. A sad day, indeed. Do you know what I saw on my way in here? A girl... In a sweater. And you know what that means. The season of exposed skin is over. Exactly. Gone are the tank tops, Ted. Gone are the cute little skirts. Gone are the sun dresses. The sun dresses, Ted! I don't think I can make it another eight months with no sun dresses.
Ted: Barney, I really... I have to grade these papers.
Barney: I'm sorry. I'll let you work. But first, a riddle: What piece of women's attire most stokes a man's desire?
Ted: A sun dress.
Barney: Correct. What lightweight outfit, pink or white, makes the front of my slacks abnormally tight?
Ted: I really have to get this done.
Barney: Of course, of course. "Sun dress", by the way.
