Rules for evil overlords

We all know that the evil overlord gets defeated in the last 10 minutes of the movie, usually because he's overlooked something vital, he's been betrayed by one of his underlings, or he's seriously underestimated the hero. If you have any aspirations to try the evil overlord business yourself, I suggest you first read this list, and you might avoid the last minute defeat. (And if you have no plans for world domination, read it anyway. It's pretty funny.)
