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.
Eagles–Giants rivalry
The Eagles–Giants rivalry is a National Football League (NFL) rivalry between the Philadelphia Eagles and New York Giants. The rivalry began in 1933 with the founding of the Eagles, and slowly strengthened when both teams came to relative prominence in the 1940s and 1950s. The two teams have played in the same division in the NFL every year since 1933. The ferocity of the rivalry can also be attributed to the geographic New York-Philadelphia rivalry, which is mirrored in Major League Baseball's Mets–Phillies rivalry and the National Hockey League's Flyers–Rangers rivalry. It is ranked by NFL Network as the number one rivalry of all-time and "Sports Illustrated" ranks it amongst the top ten NFL rivalries of all-time at number four, and according to ESPN, it is one of the fiercest and most well-known rivalries in the football community.
