Background: 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.
Context: 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.

Problem: Background: Sydney Francis Barnes (19 April 1873 - 26 December 1967) was an English professional cricketer who is generally regarded as one of the greatest ever bowlers. He was right-handed and bowled at a pace that varied from medium to fast-medium with the ability to make the ball both swing and break from off or leg. He is the quickest bowler to achieve 150 Test wickets in history. Barnes was unusual in that, despite a very long career as a top-class player, he spent little more than two seasons in first-class cricket, representing Warwickshire and Lancashire.
Context: Barnes' career began in 1888 when he was fifteen and played for a small club which had a ground behind the Galton Hotel in Smethwick. Soon afterwards, he joined Smethwick Cricket Club and played for its third team. He was taught to bowl off spin by Billy Bird, the Smethwick professional who had played for Warwickshire, and then taught himself to bowl leg spin. In due course, he was selected for the second team and had earned a place in the first team, playing in the Birmingham and District Premier League, at the start of the 1893 season. In 1894, when Barnes was a 21-year-old fast bowler, he was asked to join the ground staff of Staffordshire County Cricket Club but he found the terms unattractive. Instead, he joined Rishton Cricket Club in the Lancashire League where the pay was better than in any form of county cricket, largely because of match bonuses and collections. Wilfrid S. White commented that Barnes' career in league cricket "stands out unparalleled, unapproached, by any other player". Later in the 1894 season, Barnes was invited to play for Warwickshire, who were due to enter the County Championship in 1895. His debut was in a minor match against Cheshire at Edgbaston on 20-21 August. Barnes bowled only 8 overs, taking none for 27, and the match was drawn. On 23 August, Barnes made his first-class debut for Warwickshire against Gloucestershire at Clifton College Close Ground, except that he did not take the field as play was restricted by bad weather to just 72 overs of his team's first innings, in which they reached 102-2.
Question: What was Barnes doing during this time?
Answer:
Barnes' career began in 1888 when he was fifteen and played for a small club which had a ground behind the Galton Hotel in Smethwick.
