Edward Herrmann when he was younger was cute in that "intelligent" way...not so much now that he's gained weight, but I still LOVE his voice.
Vincent D'Onofrio is hot, but I've come to the conclusion that he's only hot in L & O: CI. In anything else he just doesn't ring my bell.
The guys I was attracted to in college would probably be a more telling barometer, but even if I had their pics I sure as heck would not post them here.
