There's something sexy about Tim White, the evening anchor at Channel 3. It's not really his looks -- he's attractive, without being gorgeous -- or his voice, which is relatively bland. It's pure intelligence. This is a man with a Ph.D., a host of awards for making documentaries, and a post as a brigadier general in the Air Force Reserve. Yes, that's a general. With all White's life experience, we don't think we're imagining the knowing twinkle in his eye when he launches into a particularly stupid segment: He's too good for this, and he's smart enough to know it.
