I would be hard pressed to make a decision on this- for sheer intelligence which I have seen from some posters it makes the matter that much harder. I guess if limited to just one, I would select naughty. If I wanted a quip I'd go with Pecker, if I wanted irrational I'd go with- well, too many selections there- if I wanted charm and appeal I'd go with ManlyBanisters (although she might be too busy baking brownies under her tarp). If I thought I'd score a sex date with them I'd select- well, once again, too many choices.
To avoid any conflicts or hurt feelings, just give me the million dollars and we'll call it even.
