Chief official White House photographer Pete Souza captured this moment aboard Air Force One on Nov. 14, 2009. The president and his team were en route to the Asia-Pacific Economic Cooperation summit in Singapore.

At the Summit, the President joked that he looked forward to hosting the 2011 Summit in Hawaii, where everyone would have to wear Hawaii shirts and grass skirts."
