'History of Rap 5': Jimmy Fallon and Justin Timberlake Spit More Rhymes

Jimmy Fallon's first week hosting "The Tonight Show" couldn't end any other way.

His friend and frequent comedy partner, Justin Timberlake, appeared on the last show of the week. The two riffed about how Timberlake and wife Jessica Biel drank all the booze in Fallon's home, and Timberlake performed "Not a Bad Thing" from his "20/20 Experience" album.
