Jimmy Fallon’s team has created another hilarious mash-up with Brian Williams, rapping Sir Mix-A-Lot’s classic “Baby Got Back.” NBC Nightly News managing editor and anchor, Brian Williams is an award-winning icon of journalistic professionalism and credibility – but ghetto he ain’t, making his delivery of Mix-A-Lot’s lines so incongruous as to be side splitting. In this ode to the booty, Bri-Wi’s edited rap gets wildly enthusiastic help from a male and a female chorus of news faces who are all the way live.
