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.
Arsenal F.C.–Manchester United F.C. rivalry
Although Arsenal and Manchester United had previously contested many significant matches, Sir Alex Ferguson believed the rivalry started in January 1987 when David Rocastle was sent off for retaliating against a foul on Norman Whiteside. It is, however, generally perceived to have begun in October 1990, when a brawl between both sides at Old Trafford resulted in both clubs being docked points in the 1990–91 First Division. The scuffle started when Arsenal's Anders Limpar, who scored the only goal of the game, contested for the ball with Manchester United defender Denis Irwin. Limpar's teammate Nigel Winterburn tackled Irwin, which prompted Brian McClair and Irwin to retaliate. Winterburn was pushed onto the advertising hoardings and all the players bar goalkeeper David Seaman partook in a 20-second mêlée. As well as a points deduction, both clubs fined several of their players, and in Arsenal's case, their manager too. Arsenal and United next faced each other at Highbury a little over a month later in the Football League Cup fourth round. 19-year-old winger Lee Sharpe scored a hat-trick as United won the tie 6–2.
