There are, in fact, corresponding ads in women's washrooms, especially bar washrooms, where one is likely not only to spend more time on the pot, but likely to be inebriated and perhaps more receptive. There are ads on the back of the stall doors, stickers on the mirrors, ads on the tampon vending machines, ads on the walls, and sometimes ads on the trendy herbal hangover cure vending machines. Thankfully usually not all at once, but it's only a matter of time.

The solution of course is a campaign of vociferous counter-graffiti - carry a sharpie in your purse, ladies! At least you know they aren't video-taping you there. Yet.
