Some context: John Griffith "Jack" London (born John Griffith Chaney; January 12, 1876 - November 22, 1916) was an American novelist, journalist, and social activist. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.
London wrote from a socialist viewpoint, which is evident in his novel The Iron Heel. Neither a theorist nor an intellectual socialist, London's socialism grew out of his life experience. As London explained in his essay, "How I Became a Socialist", his views were influenced by his experience with people at the bottom of the social pit. His optimism and individualism faded, and he vowed never to do more hard physical work than necessary. He wrote that his individualism was hammered out of him, and he was politically reborn. He often closed his letters "Yours for the Revolution." London joined the Socialist Labor Party in April 1896. In the same year, the San Francisco Chronicle published a story about the twenty-year-old London giving nightly speeches in Oakland's City Hall Park, an activity he was arrested for a year later. In 1901, he left the Socialist Labor Party and joined the new Socialist Party of America. He ran unsuccessfully as the high-profile Socialist candidate for mayor of Oakland in 1901 (receiving 245 votes) and 1905 (improving to 981 votes), toured the country lecturing on socialism in 1906, and published two collections of essays about socialism: The War of the Classes (1905) and Revolution, and other Essays (1906). Stasz notes that "London regarded the Wobblies as a welcome addition to the Socialist cause, although he never joined them in going so far as to recommend sabotage." Stasz mentions a personal meeting between London and Big Bill Haywood in 1912. In his late (1913) book The Cruise of the Snark, London writes about appeals to him for membership of the Snark's crew from office workers and other "toilers" who longed for escape from the cities, and of being cheated by workmen. In his Glen Ellen ranch years, London felt some ambivalence toward socialism and complained about the "inefficient Italian labourers" in his employ. In 1916, he resigned from the Glen Ellen chapter of the Socialist Party, but stated emphatically he did so "because of its lack of fire and fight, and its loss of emphasis on the class struggle." In an unflattering portrait of London's ranch days, California cultural historian Kevin Starr refers to this period as "post-socialist" and says "... by 1911 ... London was more bored by the class struggle than he cared to admit."
what was his experience with them like?
A: His optimism and individualism faded, and he vowed never to do more hard physical work than necessary.

Question: John William Carson (October 23, 1925 - January 23, 2005) was an American television host, comedian, writer, and producer. He is best known as the host of The Tonight Show Starring Johnny Carson (1962-1992). Carson received six Emmy Awards, the Television Academy's 1980 Governor's Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987.

Carson, an amateur astronomer, was a close friend of astronomer Carl Sagan, who often appeared on The Tonight Show. The unique way Sagan had of saying certain words, like "billions" of stars, would lead Carson to ribbing his friend, saying "BILL-ions and BILL-ions". Carson was the first person to contact Sagan's wife Ann Druyan with condolences when the scientist died in 1996. He owned several telescopes, including a top-of-the-line unit. In 1981, the minor planet 1981 EM4 was named in his honor, 3252 Johnny. Carson was shown on a 1978 segment of 60 Minutes practicing at home on a drum set given to him by close friend Buddy Rich, who was the jazz musician with the most appearances on The Tonight Show. Gore Vidal, another frequent Tonight Show guest and friend, wrote about Carson's personality in his 2006 memoir. In 1982, Carson was found to be driving his DeLorean while under the influence of alcohol. He pleaded nolo contendere to a misdemeanor charge and received a sentence of three years' probation. Carson was required to attend an alcohol program for drivers and was permitted to use his car only to drive to work and back, without transporting any persons or animals in his vehicle. Carson was an avid tennis player. When he sold a Malibu house to John McEnroe and Tatum O'Neal, the escrow terms required McEnroe to give Johnny six tennis lessons. Carson's primary tennis teacher was Bob Trapenberg, who taught him for some time, and traveled with him to Wimbledon.

Using a quote from the above article, answer the following question: How did he do as a tennis player?
HHHHHH
Answer: Carson's primary tennis teacher was Bob Trapenberg, who taught him for some time, and traveled with him to Wimbledon.

Some context: Robert Dennis Crumb (; born August 30, 1943) is an American cartoonist and musician who often signs his work R. Crumb. His work displays a nostalgia for American folk culture of the late 19th and early 20th centuries, and satire of contemporary American culture. Crumb is a prolific artist and contributed to many of the seminal works of the underground comix movement in the 1960s, including being a founder of the first successful underground comix publication, Zap Comix, contributing to all 16 issues. He was additionally contributing to the East Village Other and many other publications, including a variety of one-off and anthology comics.
Crumb's father gave him $40 when he left home after high school. His first job, in 1962, was drawing novelty greeting cards for American Greetings in Cleveland, Ohio. He stayed with the company for four years, producing hundreds of cards for the company's Hi-Brow line; his superiors had him draw in a cuter style that was to leave a footprint on his work throughout his career. In Cleveland he met a group of young bohemians such as Buzzy Linhart, Liz Johnston, and Harvey Pekar. Dissatisfied with greeting card work, he tried to sell cartoons to comic book companies, who showed little interest in his work. In 1965, cartoonist Harvey Kurtzman printed some of Crumb's work in the humor magazine he edited, Help!. Crumb moved to New York, intending to work with Kurtzman, but Help! ceased publication shortly after. Crumb briefly illustrated bubblegum cards for Topps before returning to Cleveland and American Greetings. Crumb married Dana Morgan in 1964. Nearly destitute, the couple traveled in Europe, during which Crumb continued to produce work for Kurtzman and American Greetings, and Dana stole food. The relationship was unstable as Crumb frequently went his own way, and he was not close to his son Jesse (b. 1965). In 1965 and 1966 Crumb had a number of Fritz the Cat strips published in the men's magazine Cavalier. Fritz had appeared in Crumb's work as early as the late 1950s; he was to become a hipster, scam artist, and bohemian until Crumb abandoned the character in 1969. Crumb was becoming increasingly uncomfortable with his job and marriage when in June 1965 he began taking LSD, a psychedelic drug that was then still legal. He had both good and bad trips. One bad trip left him in a muddled state for half a year, during which for a time he left Dana; the state ended when the two took a strong dose of the drug together in April 1966. Crumb created a number of his best-known characters during his years of LSD use, including Mr. Natural, Angelfood McSpade, and the Snoid.
Was Fritz a character he developed?
A:
Fritz had appeared in Crumb's work as early as the late 1950s; he was to become a hipster, scam artist, and bohemian until Crumb abandoned the character in 1969.
