NBC news anchor Brian Williams continues to sharpen his lyrical skills.

After appearing in a mash-up version of Young MC's 'Bust a Move' last year, the veteran news anchor takes on the Sugar Hill Gang's famous 1979 track 'Rapper's Delight' on 'The Tonight Show Starring Jimmy Fallon' last night (Feb. 19).

Williams was joined by fellow anchor Lester Holt for the 1979 classic. At one point, Kathie Lee Gifford cuts in with a confused, "Say what?"

The 'NBC Nightly News' managing editor must be a secret hip-hop head. Fallon has also had Williams rap to Snoop Dogg's 'Nuthin' but a 'G' Thang' and Warren G's 'Regulate.'
