In honor of A.G.T.I.'s 25th anniversary in 1921, College Night became a competition between two sides, Purple and Gold, instead of a competition between the classes.[5] Since then, both sides have adopted mascots; Purple Side adopted the cow as theirs, and Gold Side adopted the lion as theirs. Each side has a song that is sung only when members of the side join hands, forming a circle; whereas Purple Side's circle is connected 360° around, Gold Side leaves a small whole in their circle. When "circled up," the leaders of each side "ask a question" to all the other members of their respective sides.
