George Clooney and Bill O'Reilly apparently don't like each other. The animosity stems from an alleged "investigation" O'Reilly did on a Clooney-spearheaded telethon for 9/11 victims, claiming that the money was squandered. Now, O'Reilly's trying to muckrake again on Clooney's tsunami telethon, but Clooney instead tore him a new asshole. Pretty fun squabble -- check it out.
(Beware I'm linking to an extremely biased account of this spat. But Clooney's move apparently worked, and O'Reilly's gonna be on the telethon instead of bitching and whining on the sidelines.)
