Answer the question at the end by quoting:

Ernest Edward "Ernie" Kovacs (January 23, 1919 - January 13, 1962) was an American comedian, actor, and writer. Kovacs's visually experimental and often spontaneous comedic style influenced numerous television comedy programs for years after his death. Many individuals and shows, such as Johnny Carson, David Letterman, Rowan and Martin's Laugh-In, Saturday Night Live, Monty Python's Flying Circus, Jim Henson, Max Headroom, Chevy Chase, Conan O'Brien, Jimmy Kimmel, Captain Kangaroo, Sesame Street, The Electric Company, Dave Garroway, Uncle Floyd, and many others have credited Kovacs as an influence. Chevy Chase thanked Kovacs during his acceptance speech for his Emmy award for Saturday Night Live.
A frequent critic of the U.S. tax system, Kovacs owed the Internal Revenue Service several hundred thousand dollars in back taxes, due to his simple refusal to pay the bulk of them. Up to 90% of his earnings were garnished as a result. His long battles with the IRS inspired Kovacs to invest his money in a convoluted series of paper corporations in the U.S. and Canada. He would give them bizarre names, such as "The Bazooka Dooka Hicka Hocka Hookah Company". In 1961, Kovacs was served with a $75,000 lien for back taxes; that same day he bought the California Racquet Club with the apparent hope of being able to use it as a tax write-off. The property had mortgages at the time of purchase which were later paid by Edie Adams.  His tax woes also affected Kovacs's career, forcing him to take any offered work to pay his debt. This included the ABC game show Take A Good Look, appearances on variety shows such as NBC's The Ford Show, Starring Tennessee Ernie Ford, and some of his less memorable movie roles. He also filmed an unaired 1962 pilot episode for a proposed CBS series, Medicine Man (co-starring Buster Keaton, pilot episode titled "A Pony For Chris"). Kovacs's role was that of Dr. P. Crookshank, a traveling medicine salesman in the 1870s selling Mother McGreevy's Wizard Juice, also known as "man's best friend in a bottle". This was abandoned after his death, which occurred the day after filming some scenes for the pilot in Griffith Park. CBS initially intended to broadcast the show as part of a summer replacement program, The Comedy Spot, but decided against it due to problems with Kovacs's estate. The pilot is part of the public collection of the Paley Center for Media.  Some of the issues regarding Kovacs's tax problems were still unresolved years after his death. Kovacs had purchased two insurance policies in 1951; his mother was named as the primary beneficiary of them. The IRS placed a lien against them both for their cash value in 1961. To stop the actions being taken against her, Mary Kovacs had to go to Federal court. The court's early 1966 ruling resolved the issue, with the last sentence of the document reading: "Prima facie, it looks as if, within the limits of discretion permitted the government by the relevant statutes, an injustice is being done Mary Kovacs."  Adams, who married and divorced twice after Kovacs's death, refused help from celebrity friends who planned a benefit for the purpose. Saying "I can take care of my own children", and being determined to accept offers only from those who wanted to hire her for her talents, Adams managed to pay all of Kovacs' debts.

His long battles with the IRS

IN: Shane Keith Warne (born 13 September 1969) is a former Australian international cricketer, and a former ODI captain of the Australian national team. Widely regarded as one of the greatest bowlers in the history of the game, Warne was named one of the Wisden Cricketers of the Year in the 1994 Wisden Cricketers' Almanack. He was the Wisden Leading Cricketer in the World in 1997 (Notional Winner). He was named Wisden Leading Cricketer in the World for the year 2004 in the 2005 Wisden Cricketers' Almanack.

Warne missed the entire Australian summer of 2000-01 with a finger injury, and found himself battling Stuart MacGill and an in-form Colin Miller to be selected for Australia's tour of India in early 2001. MacGill was ultimately the spinner left out. Warne took 10 wickets over the three-Test series at an average of 50.50. His Indian spin counterpart Harbhajan Singh was the man of the series with 32 wickets at an average of 17.03. Australia lost the series 2-1. In the northern summer of 2001, Warne made his third Ashes tour and took 31 wickets in the five-Test series, which Australia won 4-1. He took three five-wicket hauls in the series. In the final Test at The Oval he took 11 wickets across both innings, including the 400th wicket of his Test career (Alec Stewart). He became the sixth person and the first Australian in the history of cricket to reach the milestone.  In the 2001-02 Australian summer, Australia played home series against New Zealand and against South Africa. Warne took six wickets in three Tests against New Zealand, and in the third Test in Perth made his highest career score with the bat in international cricket. He was caught at mid-wicket off the bowling of Daniel Vettori (off what was later revealed to be a no-ball) while on 99 runs, one run short of a maiden Test century. He took 17 wickets in the three Tests against South Africa--more than any other player--including a five-wicket haul (5/113) in the first innings of the first Test. Warne was again the leading wicket-taker when Australia played a three-Test series in South Africa in February and March 2002, with 20 dismissals. In February 2002, Ricky Ponting replaced Steve Waugh as captain of Australia's ODI squad. The elevation of Ponting--five years younger than Warne--appeared to extinguish any prospect of Warne ever being appointed to captain Australia.  Australia played a three-Test series against Pakistan in October 2002, held in neutral Sri Lanka and the United Arab Emirates. Warne, who had lost weight over the previous months, took 27 wickets, was named the player of the series, and was man of the match in the first Test (with 11 wickets) and the third Test (with eight wickets). He returned to Australia for the Ashes series against England, starting in November 2002. He scored a half-century (57) with the bat in the first Test, before taking 11 wickets in the first three Tests of the series. However, in an ODI in December 2002, he suffered a shoulder injury. The injury not only ruled him out of the remainder of the Ashes series, but put him in doubt for the World Cup, due to commence in February 2003.

Did he require surgery?
