Bill O'Reilly's controversial appearance on The View Thursday gave MSNBC's Keith Olbermann just the excuse he needed to let loose on the conservative pundit.
O'Reilly may have become Thursday's most talked about story after his comments caused two hosts of ABC's popular daytime show to walk off the set.
Joy Behar and Whoopi Goldberg walked off the stage of "The View" during an argument with Bill O'Reilly over the proposed Islamic center near the site of the Sept. 11 terrorist attacks.
The women objected to the Fox News Channel host saying that "Muslims killed us on 9/11."
Olbermann, who has a longstanding feud with O'Reilly, couldn't let the opportunity pass without using his "Worst Person in the World" segment to call out the Fox News host.
"Lost in that, of course, is that fact that Bill O. without the benefit of a script revealed himself to be just another Fox News bigot and Islamophobe," explained Olbermann.
"It's like asking who used to be the cleverist juvenile delinquent in a school. Now he's just parroting Gretchen Carlson and Glenn Beck over there," said Olbermann. "It's sad."
Behar used her platform on Headline News later that evening to elaborate on the controversy.
On her Headline News show Thursday night, Behar continued her O'Reilly rant, stating that he had a "pinhead moment."
She said she was "really angry ... I thought he was saying something that I construe as hate speech, frankly."
To say Muslims were responsible for 9/11, "to lump an entire group like that," is wrong, she said.
Behar told PopEater, "He's an idiot!"
