Ew! Pick up lines? Really? I don't like men who appear weak and cowardly. To me, that's how a cheesy come-on makes one look. It's one thing if you happen to think of something situationally funny to say. For the most part, however, the most successful "lines" have been to the effect of, "Hey, pretty girl. I'm So-and-so. What's your name?" or "People keep recommending that book to me. Is it really that good?" To get my number, the most successful tactic has been to engage me in a normal, pleasant conversation and simply ask for it directly before parting ways. Women are not majic tricks. There's not majic words which open us up.
