I just spent the entire day watching something called "A Very Potter Musical" and then something equally amazing called "A Very Potter Sequel" and all I can say is that while some fans out there are completely bonkers, some are completely brilliant. Completely not factual, but that's basically what makes it great.
(And the first person that gets sassy with me for finding a parody of our world entertaining is going to be glared at like they've never been glared at before.)
