When was the last time you heard a president say, "Drop the beat"? Probably never. And after Monday's visit to the White House by the cast of the Broadway musical Hamilton, you'll probably never hear it again.

The award-winning cast spent the day at the White House and performed songs from the musical for an audience that included President Barack Obama and first lady Michelle Obama. But one of the highlights was composer and show creator Lin-Manuel Miranda and President Obama in the Rose Garden doing a freestyle. 

When the president said, "Drop the beat," it was on.

Take a look at the video below:

Man, I'm gonna miss this guy.
