Some context: Lenny Bruce was born Leonard Alfred Schneider to a Jewish family in Mineola, New York, grew up in nearby Bellmore, and attended Wellington C. Mepham High School. His parents divorced when he was five years old (the documentary Lenny Bruce: Swear to Tell the Truth claims he was eight years old), and Lenny lived with various relatives over the next decade. His British-born father, Myron (Mickey) Schneider, was a shoe clerk and Lenny saw him very infrequently.
On October 4, 1961, Bruce was arrested for obscenity at the Jazz Workshop in San Francisco; he had used the word cocksucker and riffed that "to is a preposition, come is a verb", that the sexual context of come is so common that it bears no weight, and that if someone hearing it becomes upset, he "probably can't come". Although the jury acquitted him, other law enforcement agencies began monitoring his appearances, resulting in frequent arrests under charges of obscenity.  Bruce was arrested again in 1961, in Philadelphia, for drug possession and again in Los Angeles, two years later. The Los Angeles arrest took place in then-unincorporated West Hollywood, and the arresting officer was a young deputy named Sherman Block, who later became County Sheriff. The specification this time was that the comedian had used the word schmuck, an insulting Yiddish term that is an obscene term for penis. The Hollywood charges were later dismissed.  On December 5, 1962, Bruce was arrested on stage at the legendary Gate of Horn folk club in Chicago. The same year he played at Peter Cook's The Establishment club in London, and in April the next year he was barred from entering England by the Home Office as an "undesirable alien".  In April 1964, he appeared twice at the Cafe Au Go Go in Greenwich Village, with undercover police detectives in the audience. He was arrested along with the club owners, Howard and Elly Solomon, who were arrested for allowing an obscene performance to take place. On both occasions, he was arrested after leaving the stage, the complaints again pertaining to his use of various obscenities.  A three-judge panel presided over his widely publicized six-month trial, prosecuted by Manhattan Assistant D.A. Richard Kuh, with Ephraim London and Martin Garbus as the defense attorneys. Bruce and club owner Howard Solomon were both found guilty of obscenity on November 4, 1964. The conviction was announced despite positive testimony and petitions of support from - among other artists, writers and educators - Woody Allen, Bob Dylan, Jules Feiffer, Allen Ginsberg, Norman Mailer, William Styron, and James Baldwin, and Manhattan journalist and television personality Dorothy Kilgallen and sociologist Herbert Gans. Bruce was sentenced on December 21, 1964 to four months in a workhouse; he was set free on bail during the appeals process and died before the appeal was decided. Solomon later saw his conviction overturned; Bruce, who died before the decision, never had his conviction stricken. Bruce later received a full posthumous gubernatorial pardon.

Some context: Tyson Cleotis Chandler (born October 2, 1982) is an American professional basketball player for the Phoenix Suns of the National Basketball Association (NBA). Chandler was the second overall pick of the 2001 NBA draft by the Los Angeles Clippers, then was immediately traded to the Chicago Bulls. He has also played for the New Orleans Hornets, Charlotte Bobcats, Dallas Mavericks, and New York Knicks. As starting center for Dallas, he played an integral role in the franchise's first NBA championship in 2011.
Tyson Chandler was selected 2nd overall by the Los Angeles Clippers, who immediately traded his rights to the Chicago Bulls for former NBA Rookie of the Year Award recipient Elton Brand. The Bulls intended to pair Chandler with fellow high school phenomenon Eddy Curry in the front court. However, while both players had stretches of success during their time with the Bulls, they rarely coincided. In Chandler's case, back problems were a recurring issue throughout his career, particularly during the 2003-04 season. During the early part of his career, Chandler feuded with Brendan Haywood of the Washington Wizards and Amar'e Stoudemire of the Phoenix Suns. Later, although the feuds became less frequent, Chandler struggled with foul trouble, which limited his playing time.  Chandler also played a major role in the Bulls' playoff run in the 2004-05 season. Finding a role as a fourth-quarter defensive specialist, with notable game-saving blocks against stars like Paul Pierce and Carmelo Anthony, he was rewarded with a long-term deal to remain with the Chicago Bulls for the next six years, reportedly worth close to $63 million. With Curry's departure after the 2004-05 season, Chandler became the last member of the Bulls left from the Jerry Krause era.  During the 2005-2006 season, Chandler's biggest impact was on defense, but he struggled again with foul problems and averaged only 5.3 points per game. Due in part to his sub-par playoff performance and the Bulls' signing of four-time Defensive Player of the Year Ben Wallace in the off-season after the 2005-2006 season, Bulls GM John Paxson began to consider moving Chandler. On July 5, 2006, the Bulls and the Hornets verbally agreed to a trade that would send Chandler to the New Orleans Hornets in exchange for J. R. Smith and P.J. Brown. The deal was finalized the following week.
