Well we can drag the real actors into this. Chuck Norris is well... Chuck Norris. He's a martial artist, actor and all around clean living good guy. With his own infomercials, even. Kiefer Sutherland is an actor. He's also a notable drunk whose been arrested for DUI and has taken his pants off in public on occasion. Plus the only non-24 related commercial I remember him in is a Japanese Caloriemate commercial. You don't see a 'Kiefer Sutherland Total Gym', now do you?
So remember, Chuck Norris is a real guy. Jack Bauer is a fictional character. And MacGyver could beat them both.
