This is a clever parody of the old TV show "Welcome Back, Kotter" only here we have Harry Potter returning to school after 30 years to teach a bunch of derelict, young wizards who have named themselves the Sweathogwarts. Not only does our hero have to content with a bunch of crazy kids, he also has his dreaded headmaster to deal with - Draco Malfoy.
