Did you see the “Today” segment this morning exploiting the pain of the son of Paul Johnson, the American hostage in Saudi Arabia? He’s sitting there crying on the set, while Matt Lauer thanks him for being there (to spike the Nielsens). It reminded me of those Kevin Nealon “SNL” skits where he’d get a celeb to cry a la Barbara Walters and then grin into the camera at what he had wrought.
