Conan Christopher O'Brien (born April 18, 1963) is an American television host, comedian, writer, producer and performer. Since November 2010 he has hosted Conan, a late-night talk show that airs on the American cable television station TBS.

O'Brien was born in Brookline, Massachusetts, and raised in an Irish Catholic family. He served as president of the Harvard Lampoon while attending Harvard University, and was a writer for the sketch comedy series Not Necessarily the News. After writing for several comedy shows in Los Angeles, he joined the writing staff of Saturday Night Live, and later of The Simpsons. He hosted Late Night with Conan O'Brien from 1993 to 2009, followed by seven months hosting The Tonight Show with Conan O'Brien, the only person to serve as the permanent host for both NBC programs.

O'Brien was born in Brookline, Massachusetts (a suburb of Boston) to Thomas O'Brien, a physician, epidemiologist, and professor of medicine at Harvard, and Ruth O'Brien (née Reardon), an attorney and partner at the Boston firm Ropes & Gray. He is the third of six children. O'Brien's family is Irish Catholic and descends from pre-Civil War era immigrants. In a Late Night episode, O'Brien paid a visit to County Kerry, Ireland, where his ancestors originated.

The O'Brien dynasty (Irish: Uí Briain or Ua Briain; Modern: Ó Briain; IPA:oːˈbʲɾʲiənʲ) are a royal and noble house founded in the 10th century by Brian Boru of the Dál gCais or Dalcassians. After becoming King of Munster, through conquest he established himself as Ard Rí na hÉireann (High King of Ireland). Brian's descendants thus carried the name O'Brien, continuing to rule the Kingdom of Munster until the 12th century where their territory had shrunk to the Kingdom of Thomond which they would hold for just under five centuries.

In total, four O'Briens ruled in Munster, and two held the High Kingship of Ireland (with opposition). After the partition of Munster into Thomond and the MacCarthy Kingdom of Desmond by Tairrdelbach Ua Conchobair in the 12th century, the dynasty would go on to provide around thirty monarchs of Thomond until 1542. During part of this period in the late 13th century they had a rivalry with the Norman de Clare house, disputing the throne of Thomond. The last O'Brien to reign in Thomond was Murrough O'Brien who surrendered his sovereignty to the new Kingdom of Ireland under Henry VIII of the House of Tudor, becoming instead Earl of Thomond and maintaining a role in governance. Today the head carries the title of Prince of Thomond, and depending on succession sometimes also Baron Inchiquin.

Mel Brooks (born Melvin Kaminsky; June 28, 1926) is an American film director, screenwriter, composer, lyricist, comedian, actor and producer. He is best known as a creator of broad film farces and comic parodies. He began his career as a stand-up comic and as a writer for the early TV variety show Your Show of Shows. He became well known as part of the comedy duo with Carl Reiner, The 2000 Year Old Man. In middle age he became one of the most successful film directors of the 1970s, with many of his films being among the top ten money makers of the year that they were released. His most well known films include The Producers, Blazing Saddles, Young Frankenstein, History of the World, Part I and Spaceballs. More recently he has had a smash hit on Broadway with the musical adaptation of his first film, The Producers. He was married to the actress Anne Bancroft from 1964 until her death in 2005.

Brooks is a member of the short list of entertainers with the distinction of having won an Emmy, a Grammy, an Oscar and a Tony award. Three of his films ranked in the American Film Institute's list of the top 100 comedy films of all-time: Blazing Saddles at number 6, The Producers at number 11, and Young Frankenstein at number 13.

Martin Hayter Short, CM (born March 26, 1950) is a Canadian-American actor, comedian, writer, singer and producer. He is best known for his comedy work, particularly on the TV programs SCTV and Saturday Night Live. He starred in such comedic films as Three Amigos, Innerspace, Pure Luck, Jungle 2 Jungle, Mars Attacks!, Father of the Bride and Father of the Bride Part II and created the characters of Jiminy Glick and Ed Grimley.

Short, the youngest of five children, was born in Hamilton, Ontario, the son of Olive (née Hayter), a violinist, and Charles Patrick Short, a corporate executive with Stelco, a Canadian steel company. He and his siblings were raised Catholic. He had three older brothers, David (now deceased), Michael, and Brian, and one older sister, Nora.

Short's father was a Catholic from Crossmaglen, South Armagh (present-day Northern Ireland), who came to North America as a stowaway during the Irish War of Independence. Short's mother, who was the concertmaster of the Hamilton Symphony Orchestra, encouraged Martin's early creative endeavours. His eldest brother, David, was killed in a car accident in 1962, when Short was 12. His mother died of cancer when he was 17; and, two years later in 1969, his father died of complications from a stroke.

Nathaniel Read "Nate" Silver (born January 13, 1978) is an American statistician, psephologist, and writer. Silver first gained public recognition for developing PECOTA, a system for forecasting the performance and career development of Major League Baseball players, which he sold to and then managed for Baseball Prospectus from 2003 to 2009.

In 2007, writing under the pseudonym "Poblano," Silver began to publish analyses and predictions related to the 2008 United States presidential election. At first this work appeared on the political blog Daily Kos, but in March 2008 Silver established his own website, FiveThirtyEight.com. By summer of that year, after he revealed his identity to his readers, he began to appear as an electoral and political analyst in national print, online, and cable news media.

The accuracy of his November 2008 presidential election predictions—he correctly predicted the winner of 49 of the 50 states—won Silver further attention and commendation. The only state he missed was Indiana, which went for Barack Obama by 0.9%. He also correctly predicted the winner of all 35 Senate races that year.
