Who: Ben Johnson
Olympics: Seoul 1988

In 1988, Canadian Ben Johnson battled injuries to make the Olympics. His main rival, American Carl Lewis, was confident enough to declare that he would never lose to Johnson again. That’s when things got crazy. Despite the injuries, Johnson set a world record in the 100 meters and beat Lewis for the gold medal. Of course, he soon thereafter tested positive for steroids because there have never been any fast Canadians.
