The clip of the football game supposedly showing Paul Hornung scoring a touchdown is obviously inaccurate as the ball carrier is wearing a two-digit numeral. Paul Hornung wore #5 throughout his career with the Green Bay Packers, and when he retired head coach Vince Lombardi unofficially retired the number.
While everyone was watching the football game at Arnold's, Ritchie tells Ralph, "You better get over here because everybody bet on Green Bay. You could lose your shirt." Later, he confesses to his father that he's in trouble and owes a lot of money. When asked how much money he owes, Ralph only mentions the $80 he owes Bruiser.
