A student is caught watching what you called "X" in class when he didn't notice that he has almost 100% volume on with his mac book laptop computer. The weird thing is that he also put on his best earphone which he didn't hear anything from this computer.
His classmates were looking at him laughing, and booing, and he didn't even realize until he takes off his earphone. As soon as he realizes people know what he is watching, he just rush out of the class which left the laughter of his classmate.
A lesson learned here is that make sure you have no audio malfunction when you are watching something private. This is a very good lesson for everyone!
