Fox News' chairman and CEO Roger Ailes says Keith Olbermann's behavior is "over the line." At a Television Critics Assocation press tour Monday, Ailes said Olbermann takes shots at Fox's Bill O'Reilly because it boosts his ratings. Ya don't say?

Via B&C: "Clearly he has no viewers except those he gets when he attacks Fox News. He's made himself committed to continuing to attack Bill and, therefore, his family and I really think that's over the line ... It seems like the use of corporate assets for personal vendettas."

Then again, it is a league game. Am I wrong?
