"This is one of those photographs that needs some explanation. The President had been meeting with Communications Director Jennifer Palmieri, left, and Senior Communications Advisor Tara McGuinness, to prep for a radio interview. At one point, the President made a comment so humorous that Jenn and Tara bent over in laughter." (Official White House Photo by Pete Souza)
