The Tonight Show and Jimmy Fallon [1] have done it again! The late-night show released another hilarious "rap" starring NBC Nightly News anchor Brian Williams and a few special newsy guests. This time, Brian's mashup was set to Sir Mix-A-Lot's "Baby Got Back," but he's previous starred in versions for "Roll Out," [2] "Gin and Juice," [3] and "Rapper's Delight." [4] Watch the newsy "Baby Got Back" version above, this time without the overly enthusiastic Seattle woman dancing onstage [5].
