Jimmy Fallon is on fire as the new host of The Tonight Show and I feel like I've seen more from him in less than one week, than I've seen in the past decade from Leno. This video of Brian Williams rapping 'Rappers Delight' for instance, is good enough to impress McKayla Maroney.

We've seen these heavily edited videos before, splicing together words from newscasts, interviews and other clips to form a popular song; but this one from The Tonight Show starring Jimmy Fallon takes things to an entirely new level.

NBC Nightly News anchor Brian Williams spits the lyrics to 'Rappers Delight', and just like the lyrics suggest he even "brings two friends along."

Hilarious.
