Journalists love reporting that Americans are stupid, and they salivate at the thought of asking us to find the United States on a map or who we fought in the American Revolution. That's why it is rather amusing that the Los Angeles Times mistakenly claimed that George Washington only served one term in office as US president. 

LAT television critic Mary McNamara made the slip up in this April 19 article about HBO's surge in popularity when she began describing the cable network's “John Adams” miniseries (via Patterico) (all bold mine):

In his portrayal of our second president, Paul Giamatti creates a man perpetually dissatisfied, disgusted by the preening ambition of politics even as he is infected by it... [S]etting up a new government is a bureaucratic nightmare, with oversized personalities disagreeing over things both petty and fundamental. George Washington (David Morse) so quickly tired of the infighting among his Cabinet and vagaries of public opinion that he stepped down from the presidency after a single term. "I know now what it is like to be disliked," he says to Adams, his perpetually disliked vice president.
