Opening the White House Egg Roll, President Obama described the festivities as "one of the greatest White House traditions." Though Obama might be guilty of a little hyperbole, thousands of kids--including Sasha and Malia--certainly had a good time romping around on the White House lawn. Michelle Obama reminded the visitors that the theme of the day was "let's go play" and encouraged kids to eat well and stay active. The president also sat down and read Where the Wild Things Are to a group of enraptured children. Fergie sang the National Anthem at the opening of the party, which included gay and lesbian parents in attendance.
