 I read about one guy that entered a marathon, and he agreed to play by the rules, and they noticed that when the race was coming to a close, this guy comes across the finish line, no sweat, he was just acting like he had not done anything. And he won the bronze, and someone complained, and they found out the guy had started the race, ran through the forest, got on a bus, went to the place where the race ended, got off the bus, and then ran across the finish line. Needless to say, he was disqualified.
