December of that year. The bison statue and pedestal on the Oval were donated by the Class of 1932. In 1962, a student organization, known as "The Sacred Order of the Bison", brought to the campus a live bison mascot, which they named "Belshazzar". Belshazzars I, II, III, and IV lived in a pen near the fieldhouse and athletic fields and members of "The Sacred Order of the Bison" were responsible for the care of the mascot. However, in 1974, due to concerns from "The Sacred Order of the Bison" and students alike, Belshazzar IV was released from the confines of the campus pen and allowed to roam on a semi-natural ranch near Bartlesville, Oklahoma. Since 1974, Oklahoma Baptist University has had no live animal mascot. The university does have a male and a female student dress in bison mascot-animal costumes at some athletic and other special events. The newest addition to the mascot-animal costume, which previewed in the spring semester of 2013, became known as "Shaz". Students voted to name the bison mascot on the website at www.okbu.edu. The name of "Shaz" originated from a shorter form of Belshazzar, which was the original Bison mascot's name. "Ka-rip!" The "Ka-Rip" spirit chant was introduced by Fred McCaulley (Class of 1920) in 1918. It is repeated often and rapidly by OBU fans during sporting events, and memorization of "Ka-rip!" is an important part of OBU new student orientation. School song "Hymn to Alma Mater" became the official school song in 1939. Dean Warren M. Angell composed the music and Mary Ann Tisinger wrote the words. Welcome Week, Beanies and The Walk "Welcome Week" is OBU's program of orientation for all new students prior to the start of the fall semester. New students are given a green and gold beanie that is worn throughout welcome week, taught the Ka-rip! spirit chant and the school song, and introduced to college life. Students also engage in a "Serve Shawnee" service project. On the night before classes begin, new students participate in "The Walk" from the Oval to Raley Chapel, mirroring the walk taken on graduation day. Beanies and the traditions concerning them have varied over the years, but the tradition of recognizing and welcoming new students to campus has been revived yearly for over 90 years. The tradition began in the 1919–1920 school year when the incoming freshmen students were the first to wear
