At President Barack Obama's final White House Correspondents' Dinner Saturday night he walked on stage to Anna Kendrick's song "You're Going to Miss Me When I'm Gone," and smirked as he told the audience, "You know it's true." He mused about what he'll do once he becomes "couch commander" after his presidency and received both boos and applause when he hinted at who may take the stage as president at next year's Correspondents' Dinner.
