Richie,

Your Simpson's cartoon is exactly right! Nelson is laughing at the possibility that Sarah Palin would actually know some history.

Like I explained earlier, some staffer (probably paid less than minimum wage but not an undocumented worker) found a factiod on Paul Revere. The staff decided to have Sarah say it, have the media jump on her, present the factoid, and BINGO - Sarah is a historian.

Put Sarah on Face the Nation or Meet The Press with no advance questions and see how she does. Oops, she does not do unrehersed questions. Reason: She cannot think on her feet.
