At anthropology class, Ian Duncan (John Oliver) is revealed as the new teacher after the previous teacher, June Bauer (Betty White), was suspended for assaulting Jeff. Duncan clearly is not suitable for the job. When Chang (Ken Jeong) shows up, Duncan abuses the restraining order placed on Chang as revenge for Chang assaulting him in the previous year. As a result of Duncan using his "force field" to keep Chang away, Chang gets injured and obtains a restraining order against Duncan himself. Duncan calls it "mutually assured destruction" and makes amends with Chang.
