The Tonight Show Starring Jimmy Fallon is off to a funny, fantastic, and star-filled start! The new host has carried his usual hijinks over from his last gig, and we're not complaining. This week has been like a tour of his greatest hits, from a sequel to "Hashtag" to a new edition of "Ew!" Everything has been bigger and better, and Will Smith even went full-on Fresh Prince of Bel-Air for "The Evolution of Hip-Hop Dancing." In case you've been falling asleep early this week, take a look at the videos everyone is talking about.
