I began my programming class last night with an introduction of the topics for the evening. The PowerPoint slide was being shown by the projector on the screen as I described the night's agenda. The last topic for the night was error handling. As I was introducing the topic, suddenly the projector flashed a huge BSOD (Blue Screen of Death). My students thought it was just part of the presentation but no, the system BSODed on me at just the right moment, completely on its own. I couldn't have planned it better, nor could I have duplicated that if I tried. It was a funny moment that brought the point home. Sometimes, things turn out better than expected.
