One student sits down at his computer and notices that the screen is upside down (has been rotated 180 degrees through the display properties). He is instantly stunned. He gasps and shows the students next to him and behind him. Laughter breaks out as he pleads for assistance. After about ten minutes of staring blankly at the screen, wondering what to do, with other students around him just as lost but laughing as well, I started waking from my semiconscious slumber (I'm not a morning person, nor do I do a good job of paying attention in class) and realized that not a single one of the students in the room knew what to do.
