| A case for the Third Universal Cardinal Rule of Thumb: Never   be absolute, unless absolutely necessary:   A linguistics professor was lecturing to his class one day. "In   English," he said, "A double negative forms a positive. In some   languages, though, such as Russian, a double negative is still a   negative. However, there is no language wherein a double positive can   form a negative."   A voice from the back of the room piped up, "Yeah, right." |
