It's no secret that Mario Chalmers plays the role of the "little brother" on the Miami Heat. LeBron James, Dwyane Wade, and Chris Bosh have all taken turns yelling at him on the basketball court.

Press play on the clip above to hear it.

That wasn't the only funny thing that President Obama said today, either. Watch him give a shout-out to Chris "Birdman" Andersen's tattoos and mohawk in the clip below:
