Some students have caught Stuart looking at porn magazines in a newsagent; when they see him at school they spread the word and all the kids chant "porno. porno!" ...which Stuart tries to turn into "no porn. no porn!"
Sue arranges a "Staff Compulsory Late Afternoon Of Social Intercourse". Dean is embarrassed that he doesn't have a date to bring, so Stefan brings along a prostitute to pretend to be Dean's girlfriend.
Sue finds that half the female students have left the school to attend other schools and thinks this is because there are not enough good looking male teachers on staff. She threatens to fire Stefan if he doesn't start to try looking sexy.
Sue and Dean get Stuart to unknowingly take steroids to test whether they can improve the sporting performance of the students. The pills turn out to be Helen's female hormone replacement pills which causes Stuart to grow breasts.
Sue appoints Julia to be the editor of the school magazine. As none of the students contribute anything, Julia writes the entire magazine herself to prove the students are motivated and creative.
Acting Principal Sue, in panic mode because Principal Kevin Wright has announced his return, mysteriously borrows The Poisoner's Handbook from the library.
