How good is comedian Tina Fey’s impersonation of Republican Sarah Palin?

This just in, Tina Fey is not running for president.

Good enough to fool the former Alaska governor’s network of choice, according to media watchdog Mediaite.com.

Sunday, Fox aired a clip about Palin’s potential entry into the 2012 presidential race but used a picture of Fey from a Saturday Night Live skit.

Fox News released the following statement:  “This past Sunday during ‘America’s News Headquarters,’ a graphics error was made during a segment on former Alaska Governor Sarah Palin. The producer has since been disciplined and an explanation and apology will be made in the same hour next Sunday. Fox News regrets the error.”

TheWeek.com lists the goof as its best video of the week.

Heads may roll if something similar happens again, Mediaite reports.

A Fox News memo states: “Effective immediately, there is zero tolerance for on-screen errors. 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. That may include warning letters to personnel files, suspensions, and other possible actions up to and including termination, and this will all obviously play a role in performance reviews.”

Humans make mistakes, fortunately mine aren’t televised.
