Fun fact: The first two Super Bowls were not known as such. They were simply termed the "AFL-NFL World Championship Game." Sharron Hunt, daughter of Chiefs owner Lamar Hunt, was trying to speak about her Super Ball toy, and her accent inspired her father to informally term the Chiefs-Packers tilt as the "Super Bowl." The Colts-Jets matchup in 1969 was the first game to formally bear the name.
