When the cast of the acclaimed Broadway musical 'Hamilton' was visiting the White House they decide to have some fun with POTUS. 

Called “Rose Garden Freestyle,” the 103-second video features Miranda creating a freestyle rap based on words that were printed to index cards held by Obama.

 “I hope I don’t drop these cards,” the president said, before adding, “drop the beat.

"You think that's going viral?" A confident Obama asked after Miranda at the end of his rap.

Yes indeed, Mr President!
