Jimmy Fallon has my vote for best late night TV host: He is topical and hilarious, and The Roots are his house band -- what's not to love about that?

He is also not afraid to jump behind the mic and take on Justin Timberlake in a rap battle or dress in a chicken costume and perform as The Chickeneers.

Fallon hits the stage this time around in one of the most epic lip sync battles ever...well, at least since Milli Vanilli. Check it out as he throws down with Joseph Gordon Levitt and Stephen Merchant. Simply awesome.
