7. 'Whip My Hair' featuring Bruce Springsteen
Nov. 26, 2010
When Willow Smith's song "Whip My Hair" took over the airwaves, Jimmy Fallon couldn't resist a good parody. On Nov. 26, 2010, he dressed and performed as if he were Neil Young, and brought out a surprise guest -- none other than the Boss -- to make the slowed down version of the Top 40 smash unforgettable.
