Some context: The Chaser is an Australian satirical comedy group. They are known for their television programmes on the Australian Broadcasting Corporation channel. The group take their name from their production of satirical newspaper, a publication known to challenge conventions of taste. The group's motto is "Striving for Mediocrity in a World of Excellence".
In July 2006, Licciardello faced charges of "offensive conduct" from the New South Wales Police Force, after turning up at a rugby league football match between the Canterbury Bulldogs and the St George Illawarra Dragons on 14 July 2006 dressed up as a Bulldogs fan and attempting to sell fake knives, knuckledusters and balaclavas for a War on Everything sketch.  In April 2007, a 15-year-old boy duped YouTube into deleting all clips posted from The Chaser's War On Everything by claiming to be a representative of the ABC. They were later reinstated.  At the 2007 Logie Awards some of the Chaser team were "manhandled" by Crown Casino security staff on the red carpet before being closely supervised for the rest of the evening.  During Dick Cheney's visit to Australia in 2007, members of The Chaser team were included on the official list of terrorists, anarchists, and protesters deemed to pose a threat to the US Vice-President.  The Chaser team gained notoriety and considerable media attention over "The Eulogy Song", written by Chris Taylor and performed by Andrew Hansen on 17 October 2007 episode of The Chaser's War On Everything. The song satirised the media's posthumous praise of deceased celebrities, regardless of their behaviour in life, and mentioned among others John Lennon, Peter Brock, Stan Zemanek, Princess Diana, Steve Irwin, Donald Bradman, and Kerry Packer. The song attracted comment from both the media and politicians including Kevin Rudd and John Howard, the latter of whom used reference to the song in remarks during a sketch later aired on the programme.

Some context: George A. Meyer (born 1956) is an American producer and writer. Meyer is best known for his work on The Simpsons, where he led the group script rewrite sessions. He has been publicly credited with "thoroughly shap[ing]...the comedic sensibility" of the show. Raised in Tucson, Meyer attended Harvard University.
Born in Pennsylvania, United States in 1956, Meyer grew up in Tucson, Arizona. He is the eldest of eight children in a Roman Catholic family of German ancestry. His parents both worked in the real estate business. Meyer has made jokes about his somewhat unhappy childhood, stating that one common argument in his household was "which family member ruined a holiday", while his sister noted Meyer was frequently blamed for the family's problems. Due to its size, family activities were limited so Meyer watched lots of television and read Mad magazine. He was an Eagle Scout and an altar boy and wrote for the student newspaper. He grew up hoping to one day become either a priest or ballplayer. He was disinterested in television, only finding humor in Get Smart and Batman, where he appreciated its "loopy, irreverent humor."  Meyer attended Harvard University where he served as president of the Harvard Lampoon. The fact that people took humor "very seriously" at the Lampoon "changed [Meyer's] life". In 1977, he and several other Lampoon staffers wrote The Harvard Lampoon Big Book of College Life (ISBN 0385134460), a volume commissioned by Doubleday. Aside from the Lampoon, his grades at Harvard were average and he suffered several bouts of depression. He graduated in 1978 with a degree in biochemistry and was accepted into medical school, but decided not to enroll.  Meyer commented on his Roman Catholic upbringing in a 2000 New Yorker profile:  "People talk about how horrible it is to be brought up Catholic, and it's all true. The main thing was that there was no sense of proportion. I would chew a piece of gum at school, and the nun would say, 'Jesus is very angry with you about that,' and on the wall behind her would be a dying, bleeding guy on a cross. That's a horrifying image to throw at a little kid. You really could almost think that your talking in line, say, was on a par with killing Jesus."

Some context: Andres Jose Padovani Galarraga (Spanish: [an'drez gala'raga]; born June 18, 1961) is a Venezuelan former professional baseball player. He played in Major League Baseball as a first baseman for the Montreal Expos (1985-1991 and 2002), St. Louis Cardinals (1992), Colorado Rockies (1993-1997), Atlanta Braves (1998-2000), Texas Rangers (2001), San Francisco Giants (2001 and 2003) and Anaheim Angels (2004). He batted and threw right-handed. At six-foot-three and 235 pounds (1.91 m, 117 kg), Galarraga began his professional career in Venezuela at the age of 16.
During his first season in Atlanta in 1998, Galarraga silenced his critics. He proved that he could still have great power production at lower altitudes, hitting .305 with 44 home runs and 121 RBI. This made Galarraga the first player in Major League history to hit 40 or more homers in consecutive seasons for two different teams.  During 1999 spring training, Galarraga developed a sore back. Treatment from the team's trainers and team doctor included hydrobaths, massages, muscle relaxers, and stretching, but would not stop the nagging soreness. He was referred to a medical oncologist at Atlanta for a thorough physical exam and an MRI. When the diagnosis came in, the famous Galarraga smile disappeared. On his second lumbar vertebra in his lower back he had a tumor known as non-Hodgkin's lymphoma, a form of lymphatic cancer. He missed the entire 1999 season receiving cancer chemotherapy. Rockies third baseman and ex-teammate Vinny Castilla switched briefly from his traditional number 9 to number 14 on his jersey to honor Galarraga's cancer fight.  Galarraga returned to the field in the spring of the year 2000 in high spirits and good shape after undergoing chemotherapy and a strict workout routine. In his third at-bat of opening day of the 2000 season, Galarraga knocked in the winning run with a home run, and he showed his big smile again. In April and May, he was tied for first place in home runs in the National League and he was batting .300.  At the end of the season, Galarraga had batted .302 with 28 HRs and 100 RBIs. He was awarded his second National League Comeback Player of the Year Award by The Sporting News.  Galarraga asked the Braves ownership for a two-year contract, but the most that it would offer was a one-year contract. Hence, Galarraga decided to become a free agent, and he signed with the Texas Rangers for two years.
