Watch Jimmy Fallon and Will Smith Teach You About the Evolution of HipHop Dancing
Jimmy Fallon's debut as the new host of The Tonight Show brought in some familiar faces  including Robert DeNiro, Kim Kardashian, Lady Gaga, Steven Colbert, Lindsay Lohan, and special guest Will Smith. No big deal. But one of the most memorable moments was part of a nod to the '90s in which Fallon and Smith donned silver chains, patterned tees, and overalls while performing the "Evolution of Hip-Hop Dancing," which included 24 signature hip-hop moves densely packed into 3minutes. From the Robot to "the Leg Thing No One Can Do" iconic!, things went a long smoothly  until Smith got a little too into "Spank That" and had to be reminded to follow the cues. So what ultimately brought the dance routine to an end? Jimmy Fallon's twerking, of course  which you'll have to see for yourself.
