10. Mike Tyson Vs. Michael Spinks: Atlantic City, June 27, 1988
91 seconds to make a would-be baddest man on the planet, THE 'Baddest Man on the Plant'. Tyson vs. Spinks was the meeting of two undefeated heavyweights to determine who indeed was the best in the world at that time. 'Iron Mike' was the holder of the WBC, WBA and IBF belts while 'Jinx' was The Ring magazine champion. This would turn out to be the richest fight in boxing history, grossing just over $70 million. On top of that, Tyson earned a record purse of around $20 million while Spinks received $13.5 million. Not bad for less than two minutes work.
