The boys are sent away to learn "cultural sensitivity" and Mr. Garrison is back as the boys' 4th Grade Teacher. Ever since Ms. Chokosondik's untimely demise at the end of the spring season, Stan, Kyle and Cartman have been without a teacher. Principal Victoria rescues Mr. Garrison from his stint with the "booger- eating, pants crapping kindergarteners" and promotes him to teach the 4th grade. Informed that fourth graders are a little too old for Mr. Hat, Garrison comes to class with a new, and even more inappropriate, assistant.
