Day three, and Jimmy Fallon is still killing as the new host of The Tonight Show. Last night on the late-night fixture, he somehow got NBC's Nightly News anchor Brian Williams—who has built his career off of being a serious news journalist—to actually rap on the show!

Well...kind of. "Somehow got Brian Williams to rap" actually means he had his staff put together a supercut of Williams rapping "Rapper's Delight"...featuring none other than NBC Nightly News' Lester Holt. In other words, this is something you need to stop whatever you're doing right now to watch immediately. (Also worth noting: This isn't the first time Fallon has used this joke on a late night series he hosts, and, hopefully, it isn't the last.)

Is it just us, or does Williams actually have a pretty mean flow? It's not that surprising—dabbling in rapping is kind of in the family: Remember when his daughter, Allison Williams, performed Kanye West's "Stronger" on Girls?
