There are any number of valid reasons why Barack Obama didn’t place his hand over his heart during the National Anthem.
Maybe he has no heart.
Maybe he has a heart, but it’s on the wrong side of his body.
Maybe his heart is stored elsewhere, inside an urn consecrated to Satan.
Maybe he hates America and all that it stands for.
Maybe he was thinking about something else.
Maybe he’s attempting to attract Bush supporters, and will be running into doors and assaulting other heads of state in the future.
Maybe he’s trying to smoke out those who find such behavior objectionable, so they can be targeted later by his elite “Obamanator” death squads.
Maybe he was trying to distinguish himself from Hillary Clinton, by drawing attention to his chest and its relative lack of bosoms.
Maybe he had to keep his hands clasped in front of him, the better to conceal the enormous erection he always gets whenever the National Anthem is played.
Maybe he had to keep his hands clasped in front of him, the better to conceal the enormous erection he always gets whenever Hillary Clinton is nearby.
Maybe he had to keep his hands clasped in front of him, the better to control the trained marmoset living in his Dockers, who otherwise leaps out and works the crowd for change whenever it hears music of any kind.
Maybe he was deep in the Twenty-Third Meditative Cycle of the Lamasery of Asaru, to which he retreats whenever he hears either the National Anthem or Bachman Turner Overdrive, lest he otherwise automatically lapse into berserk fury and rend his garments asunder, driving his enemies before him while bellowing “Barack smash! Barack is the hand of vengeance! Glory to almighty Thor! Valhalla! Valhalla!”
Maybe he thinks that overt flag-worship is unbecoming to a politician.
