Muhammad Ali The Champion

Following her debut, Spears was credited with leading the revival of teen pop in the late 1990s. The Daily Yomiuri reported that "[m]usic critics have hailed her as the most gifted teenage pop idol for many years, but Spears has set her sights a little higher-she is aiming for the level of superstardom that has been achieved by Madonna and Janet Jackson." Rolling Stone wrote: "Britney Spears carries on the classic archetype of the rock & roll teen queen, the dungaree doll, the angel baby who just has to make a scene."  Rami Yacoub who co-produced Spears's debut album with lyricist Max Martin, commented, "I know from Denniz Pop and Max's previous productions, when we do songs, there's kind of a nasal thing. With N' Sync and the Backstreet Boys, we had to push for that mid-nasal voice. When Britney did that, she got this kind of raspy, sexy voice."  Following the release of her debut album, Chuck Taylor of Billboard  observed, "Spears has become a consummate performer, with snappy dance moves, a clearly real-albeit young-and funkdified voice ... "(You Drive Me) Crazy", her third single ... demonstrates Spears's own development, proving that the 17-year-old is finding her own vocal personality after so many months of steadfast practice." Stephen Thomas Erlewine of Allmusic referred to her music as a "blend of infectious, rap-inflected dance-pop and smooth balladry."  Spears later commented, "With ...Baby One More Time, I didn't get to show my voice off. The songs were great, but they weren't very challenging".

Oops!...I Did It Again and subsequent albums saw Spears working with several contemporary R&B producers, leading to "a combination of bubblegum, urban soul, and raga."[136] Her third studio album, Britney derived from the teen pop niche, "[r]hythmically and melodically ... sharper, tougher than what came before. What used to be unabashedly frothy has some disco grit, underpinned by Spears' spunky self-determination that helps sell hooks that are already catchier, by and large, than those that populated her previous two albums." Guy Blackman of The Age wrote that while few would care to listen to an entire Spears album, "[t]he thing about Spears, though, is that her biggest songs, no matter how committee-created or impossibly polished, have always been convincing because of her delivery, her commitment and her presence. For her mostly teenage fans, Spears expresses perfectly the conflicting urges of adolescence, the tension between chastity and sexual experience, between hedonism and responsibility, between confidence and vulnerability."

Mike Tyson The Baddest Man on the Planet

Michael Gerard "Mike" Tyson (born June 30, 1966) is a retired American boxer. Tyson was the undisputed heavyweight champion and holds the record as the youngest boxer to win the WBC, WBA and IBF world heavyweight titles. He won the WBC title when he was 20 years, 4 months and 22 days old, after defeating Trevor Berbick by a TKO in the second round. Throughout his career, Tyson became well-known for his ferocious and intimidating boxing style as well as his controversial behavior both inside and outside the ring.

He was the first heavyweight boxer to hold the WBA, WBC and IBF titles simultaneously. Tyson is considered to have been one of the better heavyweight boxers of all time. He is also the only Heavyweight boxer to individually unify the WBC, WBA and IBF titles.

Nicknamed "Iron Mike" and "The Baddest Man on the Planet", Tyson won his first 19 professional bouts by knockout, with twelve of them occurring in the first round. He unified the belts in the splintered heavyweight division in the late 1980s to become undisputed heavyweight champion of the world. Tyson became the lineal champion when he knocked out Michael Spinks in the first 91 seconds of the fight. 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.

In 1992, Tyson was convicted of raping Desiree Washington, for which he was sentenced to six years in prison but was released after serving three years. After being released from prison in 1995, he engaged in a series of comeback fights. He regained a portion of the heavyweight title, before losing it to Evander Holyfield in a 1996 fight by an 11th round TKO. Their 1997 rematch ended when Tyson was disqualified for biting off part of Holyfield's ear.
