Where can you find and attract witty guys?

I have been yzing what makes me attracted to people, and being witty seems to be a common theme. Perhaps because I'm naturally quiet, I tend to attract very "inside-the-box" guys (smart ones, dumb ones, cute ones, less cute ones, etc) who its no fun to have conversations with. Nothing turns me on more than some verbal back and forth, though! How can I entice more of the kind of guy I am interested in?
