According to Ryan Tate over at Valleywag, Chatroulette is on its way out. And according to me, the graph above of its declining use kind of resembles the pelvic area and thighs of a man who is laying down masturbating, perhaps on chatroulette. The tallest point is his erect penis, the bump below the scrotum. And those little up and down ridges? Those are his fingers, tugging at his scrotum.
