Glenn Beck, Stephen King Exchange Brutal Insults (VIDEO)

Glenn Beck and Stephen King have both written bestselling books, but the similarities stop there. The two have publicly declared their active dislike for each other, and have been lobbing insults over the past few days. Appearing on Bill O'Reilly's show last night, Glenn Beck responded to King's comments in his Entertainment Weekly column that Beck is like an "urban nut cake," a crazy person who believes that the world is going to end.

Glenn Beck brushed off Stephen King's comments, and took his own shot at King on the show, suggesting that King is jealous of the success of Beck's recent thriller, "The Overton Window." Beck on King: "He's the guy that usually, when I release my books at the same time, he's number 2."
