I was listening to Rock 101 the other day while driving between service calls. They spent about five minutes going through pick-up lines (some of which I'd heard before). Here's a few that I hadn't (the first one had my wife "in stitches" for a good five minutes).
"Just call me Milk." When she asks why, the response is: "'Cause I do your body goooo-ood".
"Do you believe in love-at-first-sight? Or do you want me to walk by again?"
"Your parents must've been aliens, 'cause it's the only way I can explain how someone as beautiful as you wound up on this planet."
"Sure, I may not be the best lookin' guy here, but I'm the only one talkin' to you!"
