Ever want to hear Brian Williams rap? On “Late Night with Jimmy Fallon,” we probably came as close as possible to seeing that. Jimmy Fallon introduced a video of Williams cut to match the lyrics of the classic Snoop Dogg rap song “Nuthin’ but a ‘G’ Thang.” Brian’s appearances came together with the instrumental track of the classic song in the background as he “rapped” briefly with it. It was a pretty convincing cut, but it really leaves watchers of the video wanting more. Now the only thing missing is Williams actually rapping.
