In 1951, the Innocents Society organized a Buffalo Head Exchange with the University of Colorado’s Heart and Dagger Society. The Heart and Dagger Society bought the buffalo head and had it mounted for $20. The buffalo came to be known as Mr. Chip, receiving its name from an ill-fated mascot from Colorado. The winner of the annual Nebraska-Colorado football game took home Mr. Chip. The last exchange was made in the fall of 1962. Nebraska won the game, but Colorado could not produce Mr. Chip because he had been permanently misplaced during their possession of him.
