So my dad showed me this, and it is hilarious so I had to share. Jimmy Fallon dressed up like Neil Young, and performs Willow Smith's 'Whip My Hair' acoustically.  And to make things even funnier, Bruce Springsteen comes out and performs with him.   Now if you like this, you'll definitely like their version of LMFAO's 'Sexy And I Know it'.

What song would you like to see Jimmy Fallon "cover"?
