Giacobbe "Jake" LaMotta (born July 10, 1921), nicknamed "The Bronx Bull" and "The Raging Bull," is an American retired professional boxer and former World Middleweight Champion. He was portrayed by Robert De Niro in the 1980 film Raging Bull.

LaMotta is an Italian-American born in New York City in the borough of the Bronx. He was forced by his father into fighting other children to entertain neighborhood adults, who threw pocket change into the ring. LaMotta's father collected the money and used it to help pay the rent. His cousin was the inventor Richard LaMotta.

In 1941, at the age of 19, LaMotta turned professional. During World War II, he was rejected for military service because of a mastoid operation on one of his ears.

LaMotta went 14-0-1 (3 KOs) as a middleweight in his first fifteen bouts before losing a highly controversial split decision to Jimmy Reeves in Reeves' hometown of Cleveland, Ohio. Chaos erupted after the decision was announced. Fights broke out around the ring and the crowd continued to boo for 20 minutes. The arena's organist tried to calm down the crowd by playing the Star Spangled Banner.

Michael Gerard "Mike" Tyson (born June 30, 1966) is a retired American professional boxer. Tyson is a former undisputed heavyweight champion of the world and holds the record as the youngest boxer to win the WBC, WBA and IBF heavyweight titles at 20 years, 4 months and 22 days old. Tyson won his first 19 professional bouts by knockout, with 12 of them occurring in the first round. He won the WBC title in 1986 after defeating Trevor Berbick by a TKO in the second round. In 1987, Tyson added the WBA and IBF titles after defeating James Smith and Tony Tucker. He was the first heavyweight boxer to simultaneously hold the WBA, WBC and IBF titles, and the only heavyweight to individually unify them.

In 1988, Tyson became the lineal champion when he knocked out Michael Spinks in the first 91 seconds of the fight. Tyson successfully defended the world heavyweight championship nine times, including victories over Larry Holmes and Frank Bruno. Tyson lost his titles to 42-to-1 underdog James "Buster" Douglas on February 11, 1990, in Tokyo, Japan, by a knockout in round 10. Tyson continued in his quest to regain the titles, defeating Donovan Ruddock twice in 1991. Tyson was then scheduled to take on the undisputed heavyweight champion Evander Holyfield but pulled out due to injury.

Sugar Ray Robinson (born Walker Smith Jr., May 3, 1921 – April 12, 1989) was an American professional boxer. Frequently cited as the greatest boxer of all time, Robinson's performances in the welterweight and middleweight divisions prompted sportswriters to create "pound for pound" rankings, where they compared fighters regardless of weight. He was inducted into the International Boxing Hall of Fame in 1990.

Robinson was 85–0 as an amateur with 69 of those victories coming by way of knockout, 40 in the first round. He turned professional in 1940 at the age of 19 and by 1951 had a professional record of 128–1–2 with 84 knockouts. Robinson held the world welterweight title from 1946 to 1951, and won the world middleweight title in the latter year. He retired in 1952, only to come back two and a half years later and regain the middleweight title in 1955. He then became the first boxer in history to win a divisional world championship five times, a feat he accomplished by defeating Carmen Basilio in 1958 to regain the middleweight championship. Robinson was named "fighter of the year" twice: first for his performances in 1942, then nine years and over 90 fights later, for his efforts in 1951. He defeated other Hall of Fame fighters such as Jake LaMotta, Carmen Basilio, Gene Fullmer, Randy Turpin, Carl 'Bobo' Olson, Henry Armstrong, Rocky Graziano and Kid Gavilan. Robinson engaged in 200 pro bouts, and his professional career lasted nearly 26 years.

David Brenner (born February 4, 1936) is an American standup comedian, actor, author, and filmmaker.

Brenner was born and raised in poor areas of Philadelphia. Unlike many of the other children in his neighborhood, he managed to stay away from too much trouble. His sense of humor led to his immense popularity during his school years, winning Brenner the title of "Class President" every year. After high school he largely hung out on the street corners for two years, followed by two years in the army, serving in the 101st Airborne and as a cryptographer of the 595th Signal Corp in Boblingen, Germany. After being discharged, he attended Temple University where he majored in mass communications, graduating with honors.

After making his national television debut on the The Tonight Show he became the show's most frequent guest with 158 appearances. Since the majority of his jokes deal with current events, mostly political, he has become somewhat of a political pundit, and has been a guest on several news-oriented shows in the recent past, and was also ranked #53 on Comedy Central Presents: 100 Greatest Stand-Ups of All Time." Brenner has appeared more often on major TV Talk Shows than any other entertainer.

Floyd Patterson (January 4, 1935 – May 11, 2006) was an American professional boxer and former Undisputed Heavyweight Champion. At 21, Patterson became the youngest man to win the world heavyweight title. He was also the first heavyweight boxer to regain the title. He had a record of 55 wins, 8 losses and 1 draw, with 40 wins by knockout. He won the gold medal at the 1952 Olympic Games as a middleweight.

Although Mike Tyson later became the youngest boxer to win a world heavyweight title, Patterson remains the youngest Undisputed Heavyweight Champion.

Born into a poor family in Waco, North Carolina, Patterson was the youngest of eleven children and experienced an insular and troubled childhood. His family moved to Brooklyn, New York, where Floyd was a truant and petty thief. At age ten, he was sent to the Wiltwyck School for Boys, a reform school in upstate New York, which he credited with turning his life around. He stayed there for almost 2 years.

At age fourteen, he started to box, trained by Cus D'Amato at his Gramercy Gym. Aged just 17, Patterson won the Gold medal in the 1952 Helsinki Olympics as a middleweight. 1952 turned out to be a good year for the young Patterson; in addition to Olympic gold Patterson won the National Amateur Middleweight Championship and New York Golden Gloves Middleweight Championship.
