Origin of the Keg of Nails
The Keg of Nails is a traveling trophy in college football, awarded to the winner of the Universities of Louisville and Cincinnati (which are now connected by Interstate 71) since 1929.
The two schools' football rivalry has stretched over the span of three conferences from the Missouri Valley Conference, to Conference USA, and most recently in the Big East Conference. It is the second oldest rivalry for Cincinnati, only behind the annual game with the Miami RedHawks.
The exchange is believed to have been initiated by fraternity chapters on the UC and UofL campuses, signifying that the winning players in the game were "tough as nails."
