South Korean épée fencer Shin Lam had a one-point lead over German Britta Heidemann in the semifinal match-up when the clock accidentally gave the German a split-second advantage. The time glitch was enough to essentially give Heidemann the victory over Lam, and then―since the official rules of fencing state that once you leave the mat you accept the result―Lam had to stay on the mat while judges reviewed their appeal...for an hour. Even still, in the end it was ruled a German victory.
