With its deft combination of humor and heart this single-camera sitcom is a both a critical and cult favorite. J.D. (Braff) is an eager doctor at Sacred Heart Hospital. With J.D. as its narrator the show frequently dips into surrealism as it shows his strange thoughts and daydreams. The rest of the characters on Scrubs are equally eccentric: best friend Turk (Faison) bossy nurse Carla (Reyes) J.D. s reluctant mentor Dr. Cox (McGinley) the anxiety-ridden ex-girlfriend Elliot (Sarah Chalke) and J.D. s arch nemesis known simply as Janitor (Neil Flynn). The fifth season earned an Emmy nod for Best Comedy Series. This season also includes the show s 100th episode a crafty homage to The Wizard of Oz.
