Who needs a pick up line? Just walk up to a woman confidently, w/o saying a word, take the cherry from her drink, balance it on my nose, pull it down with my tongue and return just the stem tied in a knot. Works pretty much every time. For the few times it doesn't I just offer to hold her coat w/o taking my hands out of pocket.
Just kidding, the cherry thing I can do, just never used it as a pick up move. Come to think of it, I've never even tried to pick up a woman ever.
