For a decade I've been chronicling our country's cavity misadventures, and I've learned several things. First is that it's dangerous to be horny. (The sheer number of sex toys removed in emergency rooms is too high to include on this list, for the most part.) Second is that men are far, far stupider than women when it comes to estimating what will fit and what will be retrievable. This is obvious, but it's nice to have the data to back it up. Third is that the human body is a wondrous thing, but the human imagination is even stronger.
