Justin & Jimmy teach us a history lesson...

If you missed Justin Timberlake's recent visit to Jimmy Fallon's set, then you missed some more greatness involving Jimmy.

It's clever, it's well done (Jimmy actually sounds like he was in Beastie Boys), and it's hilarious all at the same time. I've basically only posted videos for the last year, and more than half of them have been Jimmy Fallon. However, this one is worth the 5 minutes...
