Thanks to The Tonight Show with Jimmy Fallon, we've seen NBC Nightly News anchor Brian Williams rap before. Now B Dubs (as I like to call him) is back with another rousing rap, this time getting spliced together reciting the lyrics to the 1992 Sir Mix-a-Lot classic, "Baby Got Back." Shout out to the special news ladies of NBC, who show up for some very important backing vocals towards the end.
