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.
Wilton High School
The Wilton-Ridgefield rivalry started in 1987 when, after a heated hockey game, a bench-clearing brawl erupted. After 10 minutes of fighting, two students had to go to the hospital and nearly everyone on both teams was suspended. The fans on both sides met after the game outside of the rink (Winter Garden Ice Arena) and proceeded to fight for up to an hour. Since then neither side has backed down and at nearly every sports event between the two there is some sort of fight.
