The NBC news anchor is building up quite the back catalogue of rap covers thanks to Jimmy Fallon and his ongoing mashup series on The Tonight Show. After covering "Gin and Juice", "Rappers Delight", and "Straight Outta Compton" MC B-Will is busting the lyrics to Sir Mix-a-Lot's song about affection for large buttocks and not lying about it.
There's nothing not to like about this one, it even features Kathie Lee Gifford proclaiming "Me so horny." Sterling work, but you have to question the authenticity of how much is culled from actual, real news footage and how much Williams is complicit in this—maybe doing some redubbing while the NBC gang high-five about having another viral winner on their hands.
Anyway, don't let a stupid little thing like accusations of fakery get in the way of your enjoyment of a video on the web. Hell no.
