Ladies, what sort of do are you sporting down there? Is it a Joshua tree or a snowman? A cotton ball or a landing strip? No idea what we're talking about? Educate yourself with Playboy's "Hierarchy of Hair Down There."

And while you're at it, feel free to browse the accompanying selection of Playmates from the '70s and '80s (you know, back when Playmates actually still had "hair down there.").
