Got PMS? A glass of milk should do the trick. So says San Francisco ad agency Goodby, Silverstein, and Partners, whose new campaign touts the curative powers of milk, particularly with respect to monthly mood swings. The campaign’s web site includes a global PMS meter, a “sensitivity vocabulator,” a “video apology enhancer” (to help the user extricate himself from an irrational argument), and other tacky features. The agency’s executive director says it’s funny and self-effacing. Uh, yeah. Ha ha.
