The First Lady had Miami Heat players LeBron James, Dwayne Wade, Chris Bosh cracking up with her "video bomb" dunk at the White House.

Mrs. Obama was shooting a video piece with the players as well as their coach, Erik Spoelstra, to promote her "Let's Move" campaign to fight childhood obesity. After each takes their turn talking about eating healthy, the First Lady catches everyone off guard with her dunking ability. Enjoy!
