Watch Michelle Obama videobomb the Heat with a nasty dunk

In what has to be a first in U.S. history, we have a First Lady who can dunk.

Michelle Obama teamed up with members of the Miami Heat recently for her "Let’s Move" campaign, which is designed to help fight childhood obesity.

In a new PSA for the program, the First Lady videobombs LeBron James, Dwyane Wade, Ray Allen and Erik Spoelstra in a variety of ways, with the highlight being a slam dunk at the end of the clip.
