the HP-AU Jeannieverse - the Weasley twins, as an ongoing Academy project, research and write a book about pranks (Pranks: History, Philosophy, and Strategy). They spend a lot of time on research, even at home, which makes Ron not jealous of them, because the Academy looks more like something Percy would be interested in, from his POV (they don't even have quidditch! all Fred and George do is study!). Part of the research involves contacting Moony, Wormtail, Padfoot, and Prongs, of which only Remus replies. Other parts are tracing the history of pranking and specific pranks, the purpose of pranking (bringing happiness), and how far is too far/the ethics of pranking. The book is up to academic standards and gets published.
