Sooner, the costumed mascot of the University of Oklahoma.

Boomer and Sooner are two matching white ponies who pull the Sooner Schooner, a Conestoga wagon across the field when the University of Oklahoma football team scores. The Sooner Schooner is the true mascot of the team, bringing to mind the pioneers who settled Indian Territory during the 1889 Land Run and were the original "Sooners". The Sooner Schooner represents the University of Oklahoma as a mascot for the university and its sports teams, the Oklahoma Sooners.
