In the study group's second year at Greendale, Ben Chang was no longer a teacher and was now himself a student enrolled at the school. Much to the annoyance of his classmates, he started to make bad puns with his last name "Chang". It became a recurring idiosyncrasy of his which would continue throughout the rest of his time at the school. When Chang pretended to have amnesia he would also make puns with "Kevin", the name he was using at the time. The first occurrence of "Changuage" is the Season Two episode "Anthropology 101".
