Carol Leifer (born July 27, 1956) is an American comedian, writer, producer and actor whose career as a stand-up comedian started in the 1970s when she was in college. David Letterman discovered her performing in a comedy club in the 1980s and she has since been a guest on Late Night with David Letterman over twenty-five times as well as numerous other shows and venues. She has written many television scripts including for The Larry Sanders Show, Saturday Night Live, and most notably, Seinfeld. Leifer's "inner monologue" observational style is often autobiographical encompassing subjects about her Jewish ancestry and upbringing, coming out, same-sex marriage, relationships (having been married previously to a man and now partnered with a woman) and parenting. Leifer has become vegan, saying "I recently became vegan because I felt that as a Jewish lesbian, I wasn’t part of a small enough minority. So now I’m a Jewish lesbian vegan." Leifer is a stand-up comedian, writer, producer and actor and has been involved in such television shows as Seinfeld, It's Like, You Know..., Alright Already, and The Larry Sanders Show. With Mitchell Hurwitz, she is the creator of the short-lived The Ellen Show (2001). In 1988, she had her own special on Cinemax titled Carol Doesn't Leifer Anymore, which was produced by David Letterman. This was shortly followed by several more specials, titled Carol Leifer Comedy Cruise (1989), Really Big Show (1990), and Gaudy, Baudy, and Blue (1992). She was a writer on Saturday Night Live during the 1985/1986 season. She has performed on Late Night with David Letterman 25 times, but has only been on his show once since 1992. Leifer has also appeared on The Tonight Show Starring Johnny Carson, Dr. Katz, Politically Incorrect, Hollywood Squares, Late Night with Conan O'Brien, and The Tonight Show with Jay Leno. Her hosting duties have included four seasons of A&E's Caroline's Comedy Hour, as well as guest stints on Talk Soup and Later. She has written for the Academy Awards for most of the 21st century. Leifer starred in, created and executive-produced the WB sitcom Alright Already, called one of the "10 Best New Shows of the New Season" by the Los Angeles Times and The Washington Post. Despite good reviews, the show only ran one season. Her stand-up experience includes opening for Jerry Seinfeld and Frank Sinatra. Sinatra praised Leifer as "one funny broad!" and "I wish my mother had been that funny – I wouldn't have had to work so hard." She continues working the stand-up circuit and is reportedly writing an original picture for Dreamworks. Additionally, Leifer is a writer and co-executive producer on the CBS sitcom Rules of Engagement. In September 2007, Leifer won an auction for the handwritten notes used by Michael Vick during his apology for his role in dogfighting. Leifer began filming as a contestant for the 3rd season of Celebrity Apprentice in October 2009. However, she was the first to be eliminated on the premiere episode which aired on March 14, 2010.
