Ted: Barney I really have to grade these papers.
Barney: I'm sorry. I'll let you work...But first a riddle! What piece of women's attire stokes a man's desire?
Ted: A sundress.
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. Sundress by the way.
