Rushed Inverted Reading

If a character is doing something they want to keep secret and are suddenly interrupted (perhaps by a knock on the door), they will often grab a book to make it appear that they were reading and not scheming against the villain. When they do, they will be holding the book upside-down when the door opens because they were too rushed to ensure they were holding it properly. It makes little sense since most people store their books oriented properly. (It makes more sense if the book was just lying around somewhere.)

For added comedy, the person who arrived may take the book and rotate it for the reader's benefit.

When Hamlet enters, he notices she's holding the book upside-down, and turns it right-side-up.
