With Mitchell Hurwitz Carol Leifer is the creator of the short-lived The Ellen Show (2001). She has written for the Academy Awards for most of the 21st century. Her stand-up experience includes opening for Jerry Seinfeld and Frank Sinatra.

David Letterman discovered her performing in a comedy club in the 1980s and Carol Leifer has since been a guest on Late Night with David Letterman over twenty-five times as well as numerous other shows and venues.
