Below we have Fallon's "SNL" audition, a montage of his musical impersonations and a timeline of his entire career. What's your favorite Fallon character or sketch? We're partial to the very last video, when Fallon and Sean Hayes couldn't keep their acts together as clothing store employees.
Happy birthday, Jimmy Fallon!
