4. Mike Tyson (Boxing)
We all know Mike Tyson and his rival Evander Holyfield in the professional boxing. Holyfield defeated Tyson and won the World Heavyweight Champion title. Tyson was seeking for revenge. We thought that revenge was to take the crown from Holyfield, but we didn’t expect what Tyson would do.
During their rematch, Tyson found opportunity to get close to Holyfield (closer than we thought) and bite down his ear. If that wasn’t enough, the fight continued like nothing, but after a while and the referees called off the fight.
