Ad campaigns for maxi-pads and tampons tend to look like commercials for exotic resorts, replete with beachside strolls, yoga at sunset, and well-absorbed blue dye the color of a crystalline sea. With that Zenlike imagery on the one hand, and on the other the misguided stereotype of the crazy PMSing woman, it must be awfully confusing for men--or at least it was for one Richard Neill, whose amusing tongue-in-cheek comment about period confusion posted to the Facebook page of Bodyform, a British brand of maxipads, has now inspired a national campaign.
