Some context: Bourke's father, Frank, was serving in the RAAF and on leave in Melbourne when he played a solitary game for Richmond in 1943. A tall (193 cm) and lean (85 kg) full forward with an excellent reputation in country football, Frank returned to the city after the war and resume his playing career with Richmond. In the opening weeks of the 1946 season Frank kicked five or more goals six times in the first seven matches to lead the VFL goalkicking table. Injury curtailed further progress.
Just months after his playing retirement, Bourke was controversially pitched into the coaching position at Punt Road. The Tigers had decided to sack Tony Jewell, a premiership teammate of Bourke, just twelve months after he coached Richmond to the 1980 premiership. Although few doubted that Bourke was coaching material, the nature of his appointment and his lack of coaching experience at any level were significant hurdles to overcome. However, in 1982 Bourke took the Tigers to only their third minor premiership since the war and impressed critics with a brilliant tactical display in the semi final against Carlton. Bourke made a series of positional changes at the beginning of the game and ordered his men to slow down the Carlton play-on game, giving away fifteen-metre penalties as necessary. The Tigers won easily, and Bourke became one of only a handful of coaches to make the Grand Final in his first season.  The dream debut of a premiership was not to be. In the 1982 VFL Grand Final, Richmond led by 11 points at half time, only for Carlton to kick five unanswered goals in the third quarter and run away with the premiership by 18 points.  During the off-season, the Tigers suffered an exodus of disgruntled star players that rocked the club and lost nine of the first eleven games in 1983. Media speculation about the security of Bourke's position began in earnest, and few believed the club when Richmond denied that there was an ongoing crisis. Although the team improved in the second half of the season, further player departures were mooted if Bourke remained as coach. It seemed that his hard-training style was not appreciated by all of his charges. Reluctantly, Bourke tendered his resignation at the end of the season, well aware that he would probably have been sacked had he not done so. His winning rate over the two seasons was a very reasonable 56.5%
How many seasons did he coach for?
A: two seasons

Some context: James Edward O'Keefe III (born June 28, 1984) is an American conservative political activist. He produces secretly recorded undercover audio and video encounters with figures and workers in academic, governmental and social service organizations, purporting to show abusive or allegedly illegal behavior by employees and/or representatives of those organizations. He has been criticized for selectively editing videos to misrepresent the context of conversations and the subjects' responses, creating the false impression that people said or did things they did not. He gained national attention for his video recordings of workers at Association of Community Organizations for Reform
In September 2009, O'Keefe and his associate, Hannah Giles, published edited hidden camera recordings in which Giles posed as a prostitute and O'Keefe as her boyfriend, a law student, in an attempt to elicit damaging responses from employees of the Association of Community Organizations for Reform Now (ACORN), an advocacy organization for 40 years for persons of low and moderate income.  A Washington Post correspondent reported that O'Keefe "said he targeted ACORN for the same reasons that the political right does: its massive voter registration drives", and "Politicians are getting elected single-handedly due to this organization." ACORN mostly registered people from the Latino and African American communities.  The videos were recorded during the summer of 2009 and appeared to show low-level ACORN employees in six cities providing advice to Giles and O'Keefe on how to avoid detection by authorities of tax evasion, human smuggling and child prostitution. He framed the undercover recordings with a preface of him dressed in a "pimp" outfit, which he also wore in TV media interviews. This gave viewers, including the media, the impression that he had dressed that way when speaking to ACORN workers. However, he actually entered the ACORN offices in conservative street clothes (the sleeve of his dress shirt is visible on camera). Furthermore, the ACORN employees involved reported his activities to the police after he left. O'Keefe selectively edited and manipulated his recordings of ACORN employees, as well as distorted the chronologies. Several journalists and media outlets have expressed regret for not properly scrutinizing and vetting his work.  On April 10, 2012, the political gossip site Wonkette reported that Andrew Breitbart had signed a $120,000 contract for "life rights" by O'Keefe and Giles based on the ACORN videos. The contract was paid in monthly increments of $5,000. Giles ultimately received $32,000 before parting ways with Breitbart over what she described in legal depositions as "a conflict of visions". O'Keefe ultimately received $65,000.
