Ugly and smart - if you're smart (and ungeekish that is) someone will most likely fall in love with you eventually (all things being equal). Also, if you're beautiful and stupid, and then you're in a disfiguring accident, then you'd be stupid AND ugly, whereas if you were ugly and smart and you were in a brain-damaging accident, you ultimately wouldn't be aware of your new-found predicament, eliminating the basis for desiring to complain anyway. Win-win!
