The comparison between Jon Stewart, right, and Jon Snow (Kit Harington), Ned Stark's illegitimate son, is pretty easy. Both are audience favorites but neither of them are really considered contenders for the top spot. Each has chosen a self-imposed exile in a cold and dreary world where they selflessly fight the good fight. Stark at the wall, and Stewart on basic cable. And there are other casualties in the late-night struggle as well.
