Fox vs. Fox

Fox News firebrand Bill O'Reilly threatened yesterday to whack Rupert Murdoch in the wallet for promoting O.J. Simpson's how-I-murdered-my-wife book.

Vowing to boycott any company that advertises on Fox's two-part special hyping O.J.'s "If I Did It," O'Reilly declared: "If every American walked away from the O.J. garbage, it wouldn't happen."
