Preparations for the tug-of-war included: Watering the soil and ground where the freshmen were to stand for the contest, greasing the freshmen end of the rope, beginning the contest with upperclassmen of small stature, and gradually replacing them with much larger upperclassmen. The upperclassmen always emerged from the contest victorious. "Freshmen Initiation", "Freshmen-Upperclassmen Tug-O-War", and "Bison Orientation Police" were eliminated in the 1980s and replaced with "Welcome Week". Events hosted at OBU OBU annually hosts the OSSAA State 1A, 2A, and 3A Vocal Contest. The majority of contest activities take place in Raley Chapel, where numerous high school choirs and ensembles warm-up and perform for contest judges. OBU, over the course of the past few years, has held a two-day camp in preparation for the OMEA (Oklahoma Music Educators Association) High-School All-State Chorus auditions. Usually this event takes place the second or third weekend in July. OBU also hosts a Christian youth camp called Super Summer every year for the first three weeks of June and is attended by youth groups from everywhere in the United States. Campus organizations OBU recognizes more than 150 campus organizations with various interests and purposes, including student government, involvement, academics, music and arts, politics, social service, sports and religion. Student Government Association There are two branches of OBU's SGA: executive and legislative. The executive branch is headed by the Student Body President. The President is elected on a ballot open to the entire student body near the end of the spring semester. Anyone who is at least a junior and has a 3.0 grade point average is eligible to run for President or Vice President (see legislative section). The President works directly with the Board of Trustees and the University President. The SGA President also holds the power to sign bills for passage, or veto them. Along with the President is the Vice-President, who runs on the same ballot, the Speaker of the Senate, the Attorney General, and the Chief of Staff. Those three are appointed by the President and Vice-President, who are then approved by the Senate. The legislative branch is made up of elected senators from the student body. They hear bills and resolutions that can range from chartering official clubs on campus to allocating money for student activities. Five Senators are elected from each class, and eight at-large Senators are also elected. Furthermore, the four Class Presidents also serve as senators,
