The Sooner Schooner, a scaled-down replica of the Studebaker Conestoga wagon , is the official mascot of the sports teams of the University of Oklahoma Sooners.

Pulled by two white ponies named Boomer and Sooner, the Schooner made its debut at Owen Field in 1964, and it became the University's official mascot in 1980.

The Schooner is maintained and driven by members of the RUF/NEKS, the university's all-male spirit organization. At home football games and bowl games, the Sooner Schooner is driven onto the field in an arc that almost reaches the 50-yard line after every score.

The RUF/NEK Queen sits next to the driver, and a young member of the RUF/NEKS usually hangs by his legs off the back, waving the university's flag.

Well, usually. Sometimes, not so much
