Okay, preemptively, enough giggling. Feminine hygiene is serious business—and booming business, too. Which is why Summer's Eve has dropped this big budget yonic ode to the female genitalia, which they say shaped the course of history.

It's not often that you get to reflect upon both vaginas and ninjas at once, but when offered the chance, I'll take it. I'm not really sure what the underlying message is here, though—keep your netherparts chemically clean or men won't battle to the death over you? Or you won't rise to lead a mighty civilization? I don't think the stakes are quite that high. Then again, maybe I just haven't met a girl with genitalia worth jousting over. [via The Frisky]
