During Finals Week, UCLA students participate in "Midnight Yell", where they yell as loudly as possible for a few minutes at midnight to release some stress from studying. The quarterly Undie Run takes place during the Wednesday evening of Finals Week, when students run through the campus in their underwear or in skimpy costumes.[3] With the increasing safety hazards and Police and Administration involvement, a student committee changed the route to a run through campus to Shapiro Fountain, which culminates with students dancing in the fountain.[4] The Undie Run has spread to other American universities, including the University of Texas at Austin, Arizona State University, and Syracuse University.[citation needed]
