One tradition we're grateful to see Jimmy Fallon  taking from Late Night to The Tonight Show ? The amazing "Evolution of Dancing" sketches . In his inaugural episode as host, Fallon welcomed guest Will Smith , who helped him take the audience through the Evolution of Hip-Hop Dancing. In the skit, we get such gems as the "I'm About to Break Dance" and the "MC Hammer" and, my personal favorite, the "Fish Eye." It definitely helps that Smith is decked out in true Fresh Prince of Bel-Air style.
Can't get enough? Fallon also welcomed a parade of celebrities on his first show  and sang "Ignition (Remix)" with The Ragtime Gals .
