Some context: Mickey Charles Mantle (October 20, 1931 - August 13, 1995), nicknamed The Commerce Comet and The Mick, was an American professional baseball player. Mantle played his entire Major League Baseball (MLB) career with the New York Yankees as a center fielder and first baseman, from 1951 through 1968. Mantle was one of the best players and sluggers, and is regarded by many as the greatest switch hitter in baseball history. Mantle was inducted into the National Baseball Hall of Fame in 1974 and was elected to the Major League Baseball All-Century Team in 1999.
Mantle was born on October 20, 1931 in Spavinaw, Oklahoma, the son of Lovell (nee Richardson) Mantle (1904-1995) and lead miner Elvin Charles "Mutt" Mantle (1912-1952). He was of at least partial English ancestry; his great-grandfather, George Mantle, left Brierley Hill, in England's Black Country, in 1848.  Mutt named his son in honor of Mickey Cochrane, a Hall of Fame catcher. Later in his life, Mantle expressed relief that his father had not known Cochrane's true first name, as he would have hated to be named Gordon. Mantle spoke warmly of his father, and said he was the bravest man he ever knew. "No boy ever loved his father more", he said. Mantle batted left-handed against his father when he practiced pitching to him right-handed and he batted right-handed against his grandfather, Charles Mantle, when he practiced throwing to him left-handed. His grandfather died at the age of 60 in 1944, and his father died of Hodgkin's disease at the age of 40 on May 7, 1952.  When Mantle was four years old, his family moved to the nearby town of Commerce, Oklahoma, where his father worked in lead and zinc mines. As a teenager, Mantle rooted for the St. Louis Cardinals. Mantle was an all-around athlete at Commerce High School, playing basketball as well as football (a halfback, he was offered a football scholarship by the University of Oklahoma) in addition to his first love, baseball. His football playing nearly ended his athletic career. Kicked in the left shin during a practice game during his sophomore year, Mantle developed osteomyelitis in his left ankle, a crippling disease that was incurable just a few years earlier. Mantle's parents drove him at midnight to Oklahoma City, Oklahoma, where he was treated at the Children's Hospital with the newly available penicillin, which reduced the infection and saved his leg from requiring amputation.

Some context: O'Brien was born on April 18, 1963 in Brookline, Massachusetts. His father, Thomas Francis O'Brien, is a physician, epidemiologist, and professor of medicine at Harvard Medical School. His mother, Ruth O'Brien (nee Reardon), is a retired attorney and former partner at the Boston firm Ropes & Gray. O'Brien attended Brookline High School, where he served as the managing editor of the school newspaper, The Sagamore.
O'Brien moved to Los Angeles after graduation to join the writing staff of HBO's Not Necessarily the News. He was also a writer on the short-lived The Wilton North Report. He spent two years with that show and performed regularly with improvisational groups, including The Groundlings. In January 1988, Saturday Night Live's executive producer, Lorne Michaels, hired O'Brien as a writer. During his three years on Saturday Night Live (SNL), he wrote such recurring sketches as "Mr. Short-Term memory" and "The Girl Watchers"; the latter was first performed by Tom Hanks and Jon Lovitz. O'Brien also co-wrote the sketch "Nude Beach" with Robert Smigel, in which the word "penis" was said or sung at least 42 times. While on a writers' strike from Saturday Night Live following the 1987-88 season, O'Brien put on an improvisational comedy revue in Chicago with fellow SNL writers Bob Odenkirk and Robert Smigel called Happy Happy Good Show. While living in Chicago, O'Brien briefly roomed with Jeff Garlin. In 1989, O'Brien and his fellow SNL writers received an Emmy Award for Outstanding Writing in a Comedy or Variety Series.  O'Brien, like many SNL writers, occasionally appeared as an extra in sketches; his most notable appearance was as a doorman in a sketch in which Tom Hanks was inducted into the SNL "Five-Timers Club" for hosting his fifth episode. O'Brien returned to host the show in 2001 during its 26th season. O'Brien and Robert Smigel wrote the television pilot for Lookwell starring Adam West, which aired on NBC in 1991. The pilot never went to series, but it became a cult hit. It was later screened at The Other Network, a festival of unaired TV pilots produced by Un-Cabaret; it featured an extended interview with O'Brien and was rerun in 2002 on the Trio network.  Things changed for O'Brien in 1991, when in quick succession, an engagement fell through; Lookwell was not picked up; and, burned out, he quit Saturday Night Live. "I told Lorne Michaels I couldn't come back to work and I just needed to do something else," O'Brien recalled. "I had no plan whatsoever. I was literally in this big transition phase in my life where I decided, I'll just walk around New York City, and an idea will come to me." Mike Reiss and Al Jean, then dual showrunners of The Simpsons, called O'Brien and offered him a job. The series was notorious in the writing community at the time; O'Brien recalls "everyone wanted to be on that show, but they never hired." O'Brien was one of the first hires after the show's original crew. With the help of old Groundlings friend Lisa Kudrow, O'Brien purchased an apartment in Beverly Hills. He and Kudrow became involved as well, and Kudrow believed he should begin performing rather than writing. O'Brien disagreed, feeling that Kudrow was being overly flattering and that asserting he was happy as a writer. In his speech given at Class Day at Harvard in 2000, O'Brien credited The Simpsons with saving him, a reference to the career slump he was experiencing prior to his being hired for the show.
