Jimmy Fallon and Anne Hathaway Sing Broadway Versions of Rap Songs [VIDEO/NSFW]

Warning:  If you plan on watching this at work, you might want to turn down the volume a little bit.

Jimmy Fallon put his musical talents to work last night, as he and Anne Hathaway brilliantly and elegantly performed Broadway versions of rap songs.  (It looks someone is playing the piano for Jimmy, while he's acting.  Then again, I could be wrong.)
