So far, 'Tonight Show' host Jimmy Fallon has made 'NBC Nightly News' host Brian Williams rap (through the magic of editing) a stunning eight songs, from "Gin and Juice" to "Rapper's Delight." But last night's edition just might be the best yet, as he tackled Sir Mix-A-Lot's "Baby Got Back."

It's everything you'd want out of a Williams rap, and more. (Hint: there's some bonus Kathie Lee material.) It's certainly the most amusing, and the craftsmanship is particularly on point. Whoever actually makes these videos is definitely talented, if not insane.
