Shoo the kids off your laps now, everyone. And maybe put on headphones.This one’s mildly NSFW and definitely NSFK.

The Tonight Show is totally “ew!”

If by “ew” you mean “awesome.”

In a new sketch turned rude girl music video, Jimmy Fallon put on his infamous blonde wig and braces to play Sara, his judgemental tweenage alter ego who thinks everything pop culture is yucky. A pigtail-wearing, headgear-sporting will.i.am as mir.i.am joined her in dropping a serious beat, which is actually now available for download on iTunes.

We don’t get it, but it’s still hilarious.
