Here’s one to file under “Mistakes That Will Get You Fired”: Yesterday, Fox News reported that Sarah Palin is “50-50” on entering the 2012 presidential race. But the photo that aired with the story was of Tina Fey spoofing the likely candidate and Fox News contributor on Saturday Night Live. Now, this kind of error might pass with a smile and wink at a socialist stronghold like MSNBC, but it’s not flying at Fox. The gaffe resulted in an internal memo stating that “Mistakes by any member of the show team that end up on air may result in immediate disciplinary action against those who played significant roles in the ‘mistake chain,’ and those who supervise them.” Translation: Humiliate Caribou Barbie and it’s your head.
