I've said it before, but it came up over on Susan's blog...but if I could be any man currently living (ie, I'd look like him, and be as cool as he appears) it'd be Peter Krause. Sportsnight, Six Feet Under. He's all good looking and smooth. But not horrifyingly so.
If we include dead guys...it's Cary Grant. He's witty (in the movies), charming, sexy as hell, and generally just seems to move through life as though it were choreographed around him.
So dear readers (all 6 of you) whom would you be if you were able?
