when you're sitting the classroom listening to class presentations and all you can think about is how many minutes till you can run out of the classroom and drive to the nearest 7-11 so that you can buy a box of Oreos and eat the whole thing there and then, and then your students ask you something and you start responding with, "Oreo," but catch yourself midway and manage to turn it into "Oh, really?" except it sounds more like "ORLY?"
