Tysonâ€™s career should have been a KO many times over, but the self-proclaimed â€œBaddest Man on the Planetâ€ keeps getting back up for more. He served three years in prison after being convicted of rape in the early nineties and then, in a notorious bout, bit off part of Evander Holyfieldâ€™s ear in 1997. The one-time undisputed heavyweight champion was arrested several times and filed for bankruptcy. But â€œIron Mikeâ€ eventually revamped his public image, through comedic cameos in The Hangover and The Hangover Part II, as well as an Animal Planet reality series, Taking on Tyson. However, his true redemption came more recently as the controversial pugilist was inducted in to the boxing Hall of Fame just this week.
