Comedian Jimmy Fallon was a regular on TV's Saturday Night Live from 1998 to 2004, and now he's the host of the NBC's talk show Late Night with Jimmy Fallon. A native New Yorker, Fallon got into the entertainment business just out of college, doing stand-up comedy and specializing in impersonations. He worked in New York and then Los Angeles, and in 1998 he returned to New York for a job with Saturday Night Live. His years on the show didn't make him a comedy star, despite appearing regularly in skits and acting as Tina Fey's sidekick on the Weekend Update segments. He left the show to pursue a movie career, and soon had starring roles in Taxi (2004, co-starring Queen Latifah) and Fever Pitch (2005, opposite Drew Barrymore). A few years and a few lackluster projects later, Fallon was named to replace Conan O'Brien as the host of Late Night and he began hosting the show in March of 2009.

Extra credit: Fallon dropped out of The College of Saint Rose in Albany, New York in his last year of school, but in 2009 -- fourteen years later -- he was awarded a degree in Communications based on his professional portfolio.
