"Have Sex with a Guy with a Moustache Day," "Parking-Maid Appreciation Day," "Take Your Webmaster to Lunch Day" . . . these are actual holidays. Or at least, that's what strangers and co-workers have told us over the years. And though they might not have the celebrity or the swagger of, say, Christmas, the Banditos Misteriosos - the group behind the city's flash mob-style pillow fights, scavenger hunts, and squirt gun battles - still think they deserve a little respect.
