Chong was born at the University of Alberta Hospital in Edmonton, Alberta, on May 24, 1938, and given the name Thomas B. Kin Chong at birth. His mother was Lorna Jean (nee Gilchrist), a waitress of Scots-Irish ancestry, and his father was Stanley Chong, a Chinese truck driver who emigrated to Canada from China in the 1920s. The senior Chong had first lived with an aunt in Vancouver after arriving in Canada. As a youth, Tommy Chong moved with his family to Calgary, settling in a conservative neighbourhood Chong has referred to as "Dog Patch".
In 2003 Chong became caught up in two American investigations, code-named Operation Pipe Dreams and Operation Headhunter, which tried to trace drug traffic and users through businesses selling drug paraphernalia, mostly bongs. Operation Pipe Dream was run from Pittsburgh. US Attorney for Western Pennsylvania Mary Beth Buchanan oversaw the case. The estimated cost of Operation Pipe Dream was over $12 million and included the resources of 2,000 law enforcement officers. Fifty-five companies that sold drug paraphernalia over the Internet were the subject of the investigation, and Nice Dreams was one of them.  Chong was charged for his part in financing and promoting Chong Glass/Nice Dreams, a company started by his son Paris. His case never went to trial, as his attorney negotiated a plea agreement with the US Attorney for the Western District of Pennsylvania's Office. He admitted to distributing 7,500 bongs and water pipes on the Internet through Nice Dreams, a family company. Chong agreed to plead guilty to one count of conspiracy to distribute drug paraphernalia in exchange for non-prosecution of his wife, Shelby, and his son, Paris. Chong cooperated with the government and was the first of the Operation Pipe Dreams defendants to plead guilty.  At Chong's sentencing, Assistant U.S. Attorney for Western Pennsylvania Mary McKeen Houghton said in her arguments that Tommy Chong "used his public image to promote this crime" and marketed his products to children. U.S. Attorney Mary Beth Buchanan also was present at the sentencing in Pittsburgh and released a statement to the press stating, "there are consequences for violating the law, even if the violator is a well-known entertainer like Thomas Chong."  While Chong argued for community service and home detention at his sentencing, the district judge, Arthur J. Schwab, denied his requests and sentenced him to 9 months in federal prison, a fine of $20,000, forfeiture of $103,514, and the loss of all merchandise seized during the raid of his business. Chong served his sentence at the Taft Correctional Institution from October 8, 2003 to July 7, 2004. He was a cellmate--or "cubie"--with "The Wolf of Wall Street" Jordan Belfort, and is given credit for encouraging Belfort to write his memoirs. They have remained friends ever since.  These events were among those chronicled in a/k/a Tommy Chong (2006), a documentary by Josh Gilbert. It premiered theatrically at the New York Film Forum in New York City and won awards. His time in prison was also a main point in his book, "The I Chong".

did he go to jail?

Chong served his sentence at the Taft Correctional Institution from October 8, 2003 to July 7, 2004.



Answer the question at the end by quoting:

Robert James Fischer (March 9, 1943 - January 17, 2008) was an American chess grandmaster and the eleventh World Chess Champion. Many consider him to be the greatest chess player of all time. Bobby Fischer showed great skill in chess from an early age; at 13, he won a brilliancy known as "The Game of the Century". At age 14, he became the US Chess Champion, and at 15, he became both the youngest grandmaster up to that time and the youngest candidate for the World Championship.
Sources implying that Paul Nemenyi, a Hungarian-Jewish mathematician and physicist and an expert in fluid and applied mechanics, was Fischer's biological father were first made public in a 2002 investigation by Peter Nicholas and Clea Benson of The Philadelphia Inquirer. Throughout the 1950s, the FBI investigated Regina and her circle for her alleged communist sympathies, as well as her previous life in Moscow.  FBI files identify Paul Nemenyi as Bobby Fischer's biological father, showing that Hans-Gerhardt Fischer never entered the United States, having been refused admission by US immigration officials due to his alleged Communist sympathies. Not only were Regina and Nemenyi reported to have had an affair in 1942, but Nemenyi made monthly child support payments to Regina and paid for Bobby's schooling until his own death in 1952. Nemenyi had lodged complaints with social workers, saying he was concerned about the way that Regina was raising Bobby, to the point that, on at least one occasion, Nemenyi broke down in tears. Later on Bobby told the Hungarian chess player Zita Rajcsanyi that Paul Nemenyi would sometimes show up at the family's Brooklyn apartment and take him on outings.  After Paul Nemenyi died in 1952, Regina Fischer wrote a letter to Nemenyi's first son, Peter, asking if Paul had left money for Bobby in his will:  Bobby was sick 2 days with fever and sore throat and of course a doctor or medicine was out of the question. I don't think Paul would have wanted to leave Bobby this way and would ask you most urgently to let me know if Paul left anything for Bobby.  On one occasion, Regina told a social worker that the last time she had ever seen Hans-Gerhardt Fischer was in 1939, four years before Bobby was born. On another occasion, she told the same social worker she had traveled to Mexico to see Hans-Gerhardt in June 1942 and that Bobby was conceived during that meeting. According to Bobby Fischer's brother-in-law, Russell Targ (who was married to Joan), Regina concealed the fact that Nemenyi was Bobby's father because she wanted to avoid the stigma of an out-of-wedlock birth.

Who was Fischer's father?
