Schiller's public appearances, accompanied with a cry of "Schiller!", are a tacit challenge to other students to try to capture the bust. The currently circulating bust of Schiller was retrieved from Puebla, Mexico in the summer of 2003. In 2006, students created an online scavenger hunt, made up of a series of complex riddles about Carleton, which led participants to Schiller's hidden location. The bust was stolen from the winner of the scavenger hunt. At commencement in 2006, the holders of the bust arranged for Schiller to "graduate". When his name was called at the appropriate moment, the bust was pulled from behind the podium and displayed.
