Now I would never call myself a master of picking up the guys...But here's one that I've used once that had some good results:
"Hi."
"Hello."
"So, um, did you know that thanks to a new law based on Affirmative Action, it is now required that all Minorities be given a shot in the "random sex with strangers" field?
"Are you shitting me?
"No. (After a pause) So, how about we meet that minority quota?"
It was awkward and random and got me some pretty sweet make outs...
