President Barack Obama jokingly mimics U.S. Olympic gymnast McKayla Maroney's 'not impressed' expression while greeting members of the 2012 U.S. Olympic gymnastics teams in the Oval Office, Nov. 15, at the White House in Washington, D.C. Maroney's expression became an internet sensation when during the ceremony for her 2012 Olympic vault silver medal she was photographed giving a brief look of disappointment with her lips pursed to the side.
