get a cigarette and ask her for a light. if she says sorry i don't smoke, you say actually neither do i, i just wanted to talk to you. If she has one, you come back with a thank you and the jig is up...
or the age old "wanna go out and get some pizza and have $ex? what you don't like pizza?
or the stifler intro "hi i'm "______" and i have an 11" penis...around..."
but in all honesty, your best bet is to just go up to her, tell her your name, give her your phone number make some small talk about her and walk away with her wondering more about you. This all assuming she isn't dating someone already.
