Their hypocrisy is mind-numbing.

(Fox News) — Bill Maher uttered a female vulgarism when referring to former Republican VP candidate Sarah Palin on his HBO show Friday night.

“Did you hear this — Sarah Palin finally heard what happened in Japan and she’s demanding that we invade ‘Tsunami,’” Maher said. “I mean she said, ‘These ‘Tsunamians’ will not get away with this.’ Oh speaking of dumb tw**s, did you. . .”

Maher was offering an imagined Palin response in an apparent attempt at humor, as Palin had made no such statement.

The National Organization for Women (NOW) refused to comment on Maher’s use of the derogatory term. A rep told FOXNews.com it is a “known fact” that NOW does not correspond with FOX News.
