Five months after igniting an uproar for using the term "faggot" to refer to fellow cast member T.R. Knight, Isaiah Washington has been removed from ABC's Grey's Anatomy. The announcement did not include the usual "to pursue other opportunities" wording, and Washington himself released a statement invoking the famous line from the movie Network: "I'm mad as hell and I'm not going to take it anymore." TV Guide columnist Michael Ausiello, who broke the story on the magazine's website Thursday, quoted a source as saying that Washington's slur was not the only thing that contributed to his dismissal -- that "there was a pattern of problematic behavior" involving him. Today's (Friday) Washington Post observed that while ABC confirmed the report of the firing to some news sources, it did not to ABC News, which cited "two sources with knowledge of the situation."
