Finally, some good news for poor Dan Rather: The embattled CBS newsman won a Peabody Award Thursday for his report on abuse at Iraq's Abu Ghraib prison.

Other Peabody winners include HBO's [expletive] brilliant Deadwood and Comedy Central's [expletive] hysterical The Daily Show with Jon Stewart. [Expletive]!
