The Minnesota Vikings and the San Francisco 49ers were playing a game on October 25, 1964. The Vikings were ahead, 27-17 in the fourth quarter, when the Vikings had a fumble. Jim Marshall, playing for the Vikings, picked up the ball and started running. All the players, coaches and fans started yelling. Finally Marshall looked back, and saw the Vikings quarterback pointing the other way. Then it hit him. He was running the WRONG WAY! He threw the ball back to the quarterback. Instead, it went out of bounds, giving the 49ers two points. Marshall ran 60 yards the wrong way, without realizing it!
