The cast of Broadway's Hamilton visited the White House yesterday to present a special student workshop and performance. And while they were there, Lin-Manuel Miranda couldn't resist the opportunity to do a little white-house-themed freestyling...in the Rose Garden...with the President. A noted West Wing fan, Miranda obviously took his task very seriously, but, more surprisingly, so did President Obama. Watch both men as they give their most focused concentration to rhymes about NASA and the Oval Office (and then simultaneously mime mic drops) in the video below.

Make it go viral, it's your duty to the Commander in Chief.
