Frankly, I find a "Dress Like A Nerd Day" outrageous. Maybe because being a nerd was never cool when I was in school, though it has become sort of the "new cool", along with tech geekery. Such an event seems bent on bringing that outcast status back. I suppose inquiring nicely is the ticket--not my general method, but what the hell, it's sometimes much more satisfying to sweetly ream somebody a new one.
