7 Shinya Aoki breaks Mizuto Hirota's arm

Shinya Aoki has been accused of poor sportsmanship and being disrespectful to opponents and audiences many times in his career. But the most disgraceful instance of this behavior came at K-1 Dynamite in 2009, when he faced Mizuto Hirota. Halfway through the first round, Aoki had Hirota trapped in a hammerlock but the latter refused to tap. Aoki twisted Hirota's arm until it broke, forcing the referee to step in and call an end to the bout.

As the referee attended to Hirota, Aoki stood over him and gave him the finger. He then danced around the ring and did the same to the crowd. Needless to say, his repulsive actions enraged not only the K-1 brass but Aoki's own coach, who fired him as a coach in his gym.
