I don't think I've ever watched a "King of the Hill" all the way through. Well, not deliberately; it was on the inevitable yammering TV in a hospital waiting room where I spent a few hours earlier this year. Unlike most of my family, try as I may, I can't tune such things out when I'm trying to read. So I sequestered myself at the end of a long hallway, where passing staff favored me with curious looks. (Who would want to avoid The TV?!)
Tim Challies has watched it, though, and gleaned some awfully good observations, shared in his post Making Christianity Better or Rock N' Roll Worse? You'll be surprised at the insight in this -- huh? -- TV show.
