Greg Fitzsimmons is an American comedian known for his observational humor and his frequent appearances on late night television shows, including Late Night with Conan O'Brien, The Tonight Show with Jay Leno and Comedy Central Presents. Besides regularly touring his stand-up, Fitzsimmons has done a fair share of writing for television for shows like HBO's Lucky Louie and The Ellen DeGeneres Show. His rant-filled, at times raunchy style is reminiscent of stand-up legends such as George Carlin and has won him countless fans of classic-minded comedy since he started performing in the late 1980s. In recent years, he's started a weekly interview-based podcast and even penned his first book, Dear Mrs. Fitzsimmons, in 2010.
