When Sabrina is disappointed that her aunts won't let her stay out late to see a famous rock band (Violent Femmes), Hilda and Zelda decide to transform themselves into teenage chaperones as a compromise. But they're the ones causing the trouble when "Hillary" clashes with a security guard (played by Bubba Smith) and a high-school boy falls for "Zellery." After proving that even teenage aunts can be embarrassing, they apologize by giving Sabrina her very first flying lesson -- aboard a vacuum cleaner.
