This was due to him having gotten roofied and having an affair with another student at a Halloween party. However, his personal life took a turn for the worse when he and his wife got divorced. Chang was immediately fired but was allowed to enroll at the school as a music student with hopes of also earning a legitimate teaching degree.
This job came to an end after an anonymous source revealed to Dean Pelton that he faked his teaching credentials. Chang started his nearly decade long association with Greendale as a Spanish teacher.
He was also at one time happily married to woman named Alessandra. His known family includes a mother who refused to breast feed him as a child, a deceased twin sister named Connie whom he claimed to have eaten in utero and a brother known only as Rabbi Chang.
Benjamin Franklin 'Ben' Chang, (portrayed by actor Ken Jeong) is a long time employee of Greendale Community College who has worked at the school in various capacities.
