Freshmen orientation and "Welcome Week" were once unofficially known as "Freshmen Initiation". Freshmen were required to wear name tags and "Greencap", bow before upperclassmen, and memorize and recite "Bison Orientation Police", "Hymn to Alma Mater", "Ka-Rip", and a poem known as I am a lowly freshman.
The "Freshmen-Upperclassmen Tug-O-War" occurred the first week of "Freshmen Initiation". 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".
