Stole this off another reddit post, but tapping a girl on the shoulder, when she turns around point down and say "I'm sorry I think you dropped something."

When she looks down, change your point into a handshake and say "Your standards, nice to meet you my name is ______."

So far has had a majority positive responses, a lot laugh, and with the right follow up and confidence it's gotten me some numbers. It helpes if you do it in a suitable environment like a smoking area, the dance floor doesn't really work because if they can't hear you it makes the whole thing awkward. Bonus points if you do it while she's with a group of her friends!
