Brian Williams raps "Baby Got Back" on "The Tonight Show"

Brian Williams has a lot of different skills. He's a brilliant news anchor with a mastery of gravitas, he's shown his comedic timing on shows like "30 Rock" and "The Colbert Report" and he can also rap?

Well, not quite. This comedy mash-up masterpiece of Brian Williams rapping Sir Mix a Lot's 1986 classic "Baby Got Back" is actually the work of Jimmy Fallon, who used the brilliantly edited short to open his show Monday, which kicked off his week of shooting "The Tonight Show" in Orlando, Fla.

It's amazing to see how well-spliced this mash-up truly is, and it's mind-boggling to imagine how long it must have taken.

Two months ago, Fallon released another Brian Williams rap video, in which the NBC News anchor appeared to be performing a stoic rendition of Snoop Dogg's "Gin and Juice."
