On New Year's Eve, 1967, the Dallas Cowboys met the Green Bay Packers on the (literally) frozen tundra of Lambeau Field. In -20 degree temperatures and wind chill in the -40s, the referees' whistles stuck to their lips, forcing them to use vocal calls to officiate the game.

Down 14-17 with 4:50 left in the fourth quarter, Packers quarterback Bart Starr led his team 67 yards to the Cowboys' one-yard line. Green Bay was stuffed twice at the goal line before Starr drove into the end zone, giving the Packers their third consecutive NFL championship.

The win marked Green Bay's fifth championship in seven years, prompting legendary coach Vince Lombardi to retire. It would be almost 30 years before the team would become a dominant force again. Dallas rebounded to become one of the top teams of the 1970s, winning two Super Bowls.
