Georgia Institute of Technology
Georgia Tech students hold a heated, long and ongoing rivalry with the University of Georgia, known as Clean, Old-Fashioned Hate. The first known hostilities between the two institutions trace back to 1891. The University of Georgia's literary magazine proclaimed UGA's colors to be "old gold, black, and crimson". Dr. Charles H. Herty, then President of the University of Georgia, felt that old gold was too similar to yellow and that it "symbolized cowardice". After the 1893 football game against Tech, Herty removed old gold as an official color. Tech would first use old gold for their uniforms, as a proverbial slap in the face to UGA, in their first unofficial football game against Auburn in 1891. Georgia Tech's school colors would henceforth be old gold and white.
National Football League rivalries
The Packers–Vikings rivalry began in 1961, when the Vikings entered the league as an expansion team. The rivalry is known for being very close, both in the all-time series and in each game. It is also considered to be one of the most intense rivalries in the NFL, due these close games, the fact that both teams have often fought for the NFC North title, and the fact that the two states in which these teams reside (Minnesota and Wisconsin) have a rivalry in many sports, seen between the Big Ten rivals, the University of Wisconsin and University of Minnesota. Events such as Randy Moss mooning the Green Bay crowd in the first playoff game between these two teams (won by the Vikings), and former Packer great Brett Favre's move to the Vikings have created more resentment between these teams.
