Tina Fey's Palin impersonation foxes Fox producer

Fox News had a little difficulty this week in telling the difference between fantasy and reality. Well, more difficulty than usual.

An item on Sarah Palin's voyage round America's tourist sites, amending Wikipedia as she goes, featured an image of Tina Fey, the star of 30 Rock, spoofing Palin on Saturday Night Live in 2008.

Apparently the producer who boobed has been disciplined, but probably not in a good way. Palin is not only Fox's poster girl, but since last year she has provided political commentary for the station. It should not be difficult to tell her and Fey apart. For a start, Fey's Palin is rather more foxy than Fox's Palin.

Fey recently reprised her Palin on SNL, having a pop at "the lamestream media who twist my words by repeating them verbatim" and promising to run for office every four years. "This is my Olympics, and I'm gonna win a whole bunch of silvers," she said.

The world will be hoping that Palin does have a crack at the White House next year, if only because it will raise the quality of satire. Sending up Tim "Call me Tim" Pawlenty is not quite the same.
