My TiVo became convinced at one point that my roommate and I were lesbians. I have absolutely no idea what combination of cooking shows, Battlestar Galactica, Voltron, soccer matches, and Meerkat Manor led it to that conclusion, but for about a month it pointedly recorded every instance of late-night softcore lesbian porn it could find, along with reruns of The L Word and any made-for-TV-movie that even vaguely hinted at the idea.
