Do girls really look at personality or is it just all about brawn?

i have yet to date a girl that has only cared about the physical aspects of the relationships. In fact it is most often the opposite. Having something going for you in your outer appearance is important, especially at the beginning of a relationship, but if there's nothing beneath then it wont work. Unless your talking about one night relationships, then looks are all that matters. :) But maybe i'm an exception.
