In a video of Mormons saying lame pick-up lines, this hottie says, "I just walk up to [girls] and say, 'Hey, how's it going,' and find out more about them." So sexy. [Videogum]
My guy friends love this one as a joke (though they recently tried to translate it in a foreign language/country and failed miserably):
Guy: "Excuse me, do you know how much a polar bear weighs?"
Girl: "Uh, no..."
Guy: "Just enough to break the ice!" Buh-dum, ching!
