Problem: Background: Muhammad Ali (; born Cassius Marcellus Clay Jr.; January 17, 1942 - June 3, 2016) was an American professional boxer and activist. He is widely regarded as one of the most significant and celebrated sports figures of the 20th century. From early in his career, Ali was known as an inspiring, controversial, and polarizing figure both inside and outside the ring. Cassius Clay was born and raised in Louisville, Kentucky, and began training as an amateur boxer when he was 12 years old.
Context: Cassius Marcellus Clay Jr. () was born on January 17, 1942, in Louisville, Kentucky. He had a sister and four brothers. He was named for his father, Cassius Marcellus Clay Sr. (1912-1990), who himself was named in honor of the 19th-century Republican politician and staunch abolitionist, Cassius Marcellus Clay, also from the state of Kentucky. Clay's father's paternal grandparents were John Clay and Sallie Anne Clay; Clay's sister Eva claimed that Sallie was a native of Madagascar. He was a descendant of slaves of the antebellum South, and was predominantly of African descent, with smaller amounts of Irish and English heritage. His father painted billboards and signs, and his mother, Odessa O'Grady Clay (1917-1994), was a domestic helper. Although Cassius Sr. was a Methodist, he allowed Odessa to bring up both Cassius Jr. and his younger brother Rudolph "Rudy" Clay (later renamed Rahman Ali) as Baptists. Cassius Jr. attended Central High School in Louisville.  Clay grew up amid racial segregation. His mother recalled one occasion when he was denied a drink of water at a store--"They wouldn't give him one because of his color. That really affected him." He was also affected by the 1955 murder of Emmett Till, which led to young Clay and a friend's taking out their frustration by vandalizing a local railyard.  Clay was first directed toward boxing by Louisville police officer and boxing coach Joe E. Martin, who encountered the 12-year-old fuming over a thief's having taken his bicycle. He told the officer he was going to "whup" the thief. The officer told Clay he had better learn how to box first. Initially, Clay did not take up Martin's offer, but after seeing amateur boxers on a local television boxing program called Tomorrow's Champions, Clay was interested in the prospect of fighting. He then began to work with trainer Fred Stoner, whom he credits with giving him the "real training", eventually moulding "my style, my stamina and my system". For the last four years of Clay's amateur career he was trained by boxing cutman Chuck Bodak.  Clay made his amateur boxing debut in 1954 against local amateur boxer Ronnie O'Keefe. He won by split decision. He went on to win six Kentucky Golden Gloves titles, two national Golden Gloves titles, an Amateur Athletic Union national title, and the Light Heavyweight gold medal in the 1960 Summer Olympics in Rome. Clay's amateur record was 100 wins with five losses. Ali said in his 1975 autobiography that shortly after his return from the Rome Olympics, he threw his gold medal into the Ohio River after he and a friend were refused service at a "whites-only" restaurant and fought with a white gang. The story was later disputed, and several of Ali's friends, including Bundini Brown and photographer Howard Bingham, denied it. Brown told Sports Illustrated writer Mark Kram, "Honkies sure bought into that one!" Thomas Hauser's biography of Ali stated that Ali was refused service at the diner but that he lost his medal a year after he won it. Ali received a replacement medal at a basketball intermission during the 1996 Olympics in Atlanta, where he lit the torch to start the games.
Question: Did he end up boxing during this time?
Answer: He then began to work with trainer Fred Stoner, whom he credits with giving him the "real training",

Background: Dangerfield was born in Babylon, in Suffolk County, Long Island, New York. He was the son of Jewish parents, Dorothy "Dotty" (Teitelbaum) and the vaudevillian performer Phil Roy (Phillip Cohen). His mother was born in Hungary. Dangerfield's father was rarely home; Rodney would normally see him only twice a year.
Context: On Sunday, March 5, 1967, The Ed Sullivan Show needed a last-minute replacement for another act, and Dangerfield became the surprise hit of the show.  Dangerfield began headlining shows in Las Vegas and continued making frequent appearances on The Ed Sullivan Show. He also became a regular on The Dean Martin Show and appeared on The Tonight Show a total of 35 times. One of his quips as a standup comedian was, "I walked into a bar the other day and ordered a drink. The bartender says, 'I can't serve you.' I said, 'Why not? I'm over 21!' He said, 'You're just too ugly.' I said as always, 'Boy I tell you, I get no respect around here'." The "no respect" phrase would come to define his act in the years that followed.  In 1969, Rodney Dangerfield teamed up with longtime friend Anthony Bevacqua to build the Dangerfield's comedy club in New York City, a venue he could now perform in on a regular basis without having to constantly travel. The club became a huge success, and has been in continuous operation for nearly 50 years. Dangerfield's was the venue for several HBO shows which helped popularize many stand-up comics, including Jerry Seinfeld, Jim Carrey, Tim Allen, Roseanne Barr, Robert Townsend, Jeff Foxworthy, Sam Kinison, Bill Hicks, Rita Rudner, Andrew Dice Clay, Louie Anderson, Dom Irrera and Bob Saget.  His 1980 comedy album, No Respect, won a Grammy Award. One of his TV specials featured a musical number, "Rappin' Rodney", which would appear on his 1983 follow-up album, Rappin' Rodney. In December 1983, the "Rappin' Rodney" single became one of the first Hot 100 rap records, and the associated video was an early MTV hit. The video featured cameo appearances by Don Novello (aka Father Guido Sarducci) as a last rites priest munching on Rodney's last meal of fast food in a styrofoam container and Pat Benatar as a masked executioner pulling a hangman's knot. The two appear in a dream sequence where Dangerfield is condemned to die and doesn't get any respect, even in Heaven, as the gates close without his being permitted to enter.
Question: Did he invite other comedians to the club?
