The rules of football specify that if, during a match, a flying saucer powered by aliens supporting the HOME side appears above the field, steals the ball, and substitutes for it a spherical robot which rolls towards the AWAY team's goal, exploding immediately after scoring and injuring the goal keeper, that the goal will be scored as own goal against the HOME side. If, however, the goal keeper is unhurt, a corner is awarded against the HOME side. This rule was invoked a record seventeen times during the notorious Hove Albion versus Tottenham Hotspurs game in 1958.
