OMG, so late last year, Jimmy Fallon invited Stephen Colbert (he's another comedian, if you weren't sure) to cover "Friday" with him and the roots.  It may be the best cover of "Friday" ever.  Maybe not.  You should let us know if you think there's a better one out there, but we vote that this one goes in the "Friday" hall of fame.  Watch it here.
