Oh, dear God. In case you somehow missed this today, let's just go ahead and file this one under Best. Damn. Clip. Ever. Seriously. Jimmy Fallon is a genius. We would have never guessed in a thousand years that the inane, grating irritation known as "Whip My Hair" had any redeemable qualities, but Fallon somehow, miraculously, found them -- and that's even without convincing the Boss to channel his '70s-era self and contribute his lovably gruff harmonies! Nicely done, sir.
