If your pick-up line — whether it’s “Hi my name is Pat” or “How much does a polar bear weigh? Enough to break the ice!” — actually turns into a conversation, don’t assume you’re on the home stretch. Nope, you could still screw things up royally. Like talking about the weather, for example, or the heat of the room. We’d also avoid the topics of astrology, college majors, exes, reproductive rights legislation, shopping, infidelity, and children. Safe topics include: the bar (et cetera) that you are in, if he or she lives in the neighborhood, what he or she does for a living, some inane law your mayor recently passed, the movie you just saw, his or her darts skills, the flossing-before-OR-after-brushing conundrum, HBO, mullet websites, and how much a polar bear does, actually, weigh.
