You may remember Justin Timberlake and Jimmy Fallon's "History Of Rap" from last year — it was perhaps one of the greatest late-night clips of the last decade. Last night, Timberlake was back on Late Night to promote the upcoming Friends With Benefits, and wouldn't you know it — they just had to team up with The Roots again for a marvelous medley guaranteed to make your morning a little better.
