The first Spirit Rider horse, a black mare named Della, was owned by John Beall Jr., who served as the original Spirit Rider at OSU. When Beall left OSU, the university decided to keep the tradition alive. In 1988, the school bought its own black horse and through a contest put on by the school newspaper, The Daily O'Collegian, and won by OSU Senior Scott Townsend, "Bullet" was adopted as the name of the horse. In 2003, Bullet I was retired and OSU broke in another black horse to roam the sidelines. Bullet II died shortly before the beginning of the 2005 football season and was replaced by a third Bullet, who still serves with the Spirit Rider program today.
In addition to riding Bullet during football games, the Spirit Rider is charged with the task of taking care of the horse, such as cleaning Bullet's stall at the OSU Equine Center, feeding and exercising Bullet every day and bathing Bullet three times a week.
In 2001, Bullet was one of three finalists for the MD Barns Silver Spur Award presented by the American Quarter Horse Association. The award honors American Quarter Horses that have made a significant impact on the lives of others and created a favorable perception of the breed.
