Stan performs the technique on his own dog Sparky in front of his parents and their friends during a book club meeting, for which he is grounded for ten months.
Stan cannot understand why he is being punished, as his parents are too embarrassed to explain sexual stimulation to him and decide that the school should be responsible for teaching sex education.
The boys try talking to Chef, the only person who actually has had much sexual experience, but he (who was opposed to the sex ed class and wanted the children to keep their naivety) does not tell them anything.
As a result, Ms. Choksondik says they should start teaching kindergarten students about sex education and Mr. Garrison spearheads those lessons in an overtly erotic way, much to Chef's outrage.
Ms. Choksondik apologizes to the girls for not telling them that an STD is transmitted through sexual intercourse, believing it had been implied when she first told them.
Chef, however, states that the parents are to blame since they were so quick to let the schools handle sex education and leaving it in the hands of either someone with little experience (Mr. Mackey), someone with a negative view (Ms. Choksondik), or "a complete pervert" (Mr. Garrison, who is offended at being singled out) rather than teach it to their kids themselves.
