In football, a perfect hat trick occurs when a single player scores three goals in a single game, one with their head, one with their left foot, and one with their right foot. Tapins and penalties are also included. The feat is rare but not impossible. There have been 37 players who have scored a hat trick in the NFL (including playoffs), with only nine doing so more than once. The first known case of a player scoring a "hat trick" occurred on October 7, 1879, when John Montgomery, who played center for Princeton University, scored three times in a 9-7 win over Harvard. He did this using all parts of the body except his hands, which was legal at the time. The last known occurrence before 1950 was by Gordon Hill of the Chicago Bears in a game against the Philadelphia Eagles. From then until now, no one has been able to duplicate Montgomery's feat. The first known case of a woman scoring a "hat trick" occurred on September 12, 1930, when Margaret "Maggie" Dixon of Millbrook College (now Millersville University) scored three times in a 10-7 win over Ursuline College. Like Montgomery, she used only her head and shoulders as weapons. Maggie went on to score another hat trick eight years later for her school team.
