It is just as well Sarah Palin was not elected vice president of the US - otherwise she would have doubtless got lost on her way to work.
The former Republican vice-presidential nominee got the most famous address in Washington DC wrong in another public blunder.
Speaking at the Values Voter Summit in the US capital, Palin said: "Truth was an endangered species at 1400 Pennsylvania Avenue".
The White House is located at 1600 Pennsylvania Avenue.
Number 1400, a number of blocks away, is occupied by the 5 star Willard Hotel.
The former Governor of Alaska made the error in a speech that accused President Obama of "telling lies" after speaking at length about the abuse of truth in US politics.
Palin later poked fun at herself on Twitter, writing: "Doggone it! That explains why my Christmas cards keeps (sic) getting returned!"
The politician made headlines with her infamous gaffes during the 2008 presidential election when she supported John McCain on the campaign trail.
Palin appeared to be unsure of what the role of vice president would entail, and could not name any newspaper she read when questioned by a reporter.
In 2011, she said that the US should stand with "our North Korean allies" in a radio interview, appearing to confuse North and South Korea.
Most recently, she called fellow ex-governor Jesse Ventura a "jackass" and used an analogy comparing Obama to a domestic abuser harming his "battered wife", the US.
