He first gained national exposure on Saturday Night Live in which he earned an Emmy Award and later went on to star in a number of critically and commercially successful comedic films, including Caddyshack (1980), Ghostbusters (1984), and Groundhog Day (1993).

Murray was born and raised in Wilmette, Illinois, a northern suburb of Chicago, the son of Lucille (née Collins), a mail room clerk, and Edward Joseph Murray II, a lumber salesman. Murray's father died in 1967 from complications of diabetes when Bill was 17 years old. Murray, along with his eight siblings, was raised in an Irish American family. Three of his siblings are actors: John Murray, Joel Murray and Brian Doyle-Murray. A sister, Nancy, is an Adrian Dominican nun in Michigan, who has traveled the United States in a one-woman programme, portraying St. Catherine of Siena.

David Michael Letterman (born April 12, 1947) is an American television host and comedian. He hosts the late night television talk show, Late Show with David Letterman, broadcast on CBS. Letterman has been a fixture on late night television since the 1982 debut of Late Night with David Letterman on NBC.

In 1996, David Letterman was ranked #45 on TV Guide's 50 Greatest TV Stars of All Time.

Letterman was born in Indianapolis, Indiana. His father, Harry Joseph Letterman (April 1915 – February 1973), was a florist of British descent; his mother Dorothy Letterman (née Hofert, now Dorothy Mengering), a Presbyterian church secretary of German descent, is an occasional figure on the show, usually at holidays and birthdays.

Emo Philips is an American entertainer and comedian born in the Chicago suburb of Downers Grove. Much of his standup comedy stems from the use of paraprosdokians and garden path sentences spoken in a wandering falsetto tone of voice and a confused, childlike delivery of his material to produce the intended comic timing in a manner invoking the 'wisdom of children' or the idiot savant.

Philips has recorded three comedy albums. His album E=mo², recorded live at Caroline's in New York City, won the 1985 New Music Award for best comedy album. It was later re-released along with his Live at the Hasty Pudding Theatre album on a single CD. He also released an album called Emo in 2001. A joke of his was voted funniest religious joke ever in a 2005 online poll. In 2006, he appeared at the Newbury Comedy Festival. He was included in the top 50 of E4's 100 Greatest Comedians, and also appeared number 54 on Channel 4's top 100 greatest standups.

Aside from Philips' long career as a standup comic, he has been featured in acting roles on television series such as Miami Vice and The Weird Al Show. He has also recently appeared on British television, appearing as a guest on the panel game 8 Out of 10 Cats. Philips has several voiceover credits, including work on the animated series Dr. Katz, Professional Therapist; Home Movies; Space Ghost: Coast to Coast; Adventure Time; and the voice of Dooper in the animated series Slacker Cats.

Donald Jay "Don" Rickles (born May 8, 1926) is an American stand-up comedian and actor. A frequent guest on The Tonight Show Starring Johnny Carson, Rickles has acted in comedic and dramatic roles, but is best known as an insult comic.

Rickles was born in the New York City borough of Queens to Max Rickles, who had emigrated in 1902 with his parents Joseph and Frances Rickles from Kaunas, Lithuania (then in the Russian Empire), and Etta (Feldman) Rickles, born in New York to immigrant parents from the Austrian Empire. His family was Jewish and spoke Yiddish at home. Rickles grew up in the Jackson Heights area.

After graduating from Newtown High School, Rickles enlisted in the U.S. Navy and served during World War II on the USS Cyrene as a seaman first class. He was honorably discharged in 1946. Two years later, he studied at the American Academy of Dramatic Arts and then played bit parts on television. Frustrated by a lack of acting work, Rickles began doing stand-up comedy. He became known as an insult comedian by responding to his hecklers. The audience enjoyed these insults more than his prepared material, and he incorporated them into his act. When he began his career in the early 1950s he started calling ill-mannered members of the audience a "hockey puck". His style was similar to an older insult comic, "Mr. Warmth" Jack E. Leonard, though Rickles denies that Leonard influenced his style.

Thomas James "Tom" Snyder (May 12, 1936 – July 29, 2007) was an American television personality, news anchor and radio personality best known for his late night talk shows The Tomorrow Show, on the NBC television network in the 1970s and 1980s, and The Late Late Show, on the CBS Television Network in the 1990s. Snyder was also the pioneer anchor of the primetime NBC News Update, in the 1970s and early 1980s, which was a one-minute capsule of news updates in primetime.

Snyder was born in Milwaukee, Wisconsin to parents Frank and Marie Snyder. He received a Catholic upbringing and attended St. Agnes Elementary School and graduated from Jesuit-run Marquette University High School. He attended Marquette University, after which he had originally planned to study medicine and become a doctor.

Snyder had loved radio since he was a child and at some point changed his field of study from pre-med to journalism. He once told Milwaukee Journal Sentinel reporter Tim Cuprisin that broadcasting became more important to him than attending classes, and he skipped a lot of them. Snyder began his career as a radio reporter at WRIT (unrelated to the present-day FM station) in Milwaukee and at WKZO in Kalamazoo (where he was fired by John Fetzer) in the 1950s. For a time he worked at Savannah, Georgia AM station WSAV (now WBMQ).
