Oh man, the character Temperance "Bones" Brennan totally does it for me too, there's something remarkably geeky about obsessing over a TV character but I'm guilty there. All I know about the actress Emily Deschanel is that her sister Zooey is also an actress.
Backing out of the telly-box for a second, I haven't met an awful lot of brainy girls in real life, but yeh they're hot. I like glasses too, and grammar-nazi--girls. Like every other desireable girl though, they always seems to have a boyfriend.
