Boomer and Sooner are two mascots of the University of Oklahoma and its sports teams, the Oklahoma Sooners. The main mascot present at football games is the Sooner Schooner, a Conestoga wagon, pulled by two crème white ponies, Boomer and Sooner. At certain events, there is not sufficient room for the wagon with the live ponies, or live animal mascots may be prohibited by the rules of the venue.
