The continuing adventures of the human lightbulb

In class today, one of my students had turned into a lightbulb. I didn't want to make a big deal about it, but he was on, and it was making it difficult to see the projected image. I asked him to turn himself off, and he very abashedly did.

After class, I asked him what happened. He said that he wasn't sure. He woke up yesterday morning, and he was a lightbulb. He had had trouble falling asleep yesterday until he figured out how to turn himself off. On the other hand, once his alarm went off, he just reversed the process, and had no problem getting up and about in the morning, which, evidentially is uncommon. (From his participation in class, I can attest that this is a problem.)

He wasn't quite sure what to make of all of this, but he's a college student, so he just swings with the punches... It does sort of mean that he has to quit the lacrosse team this season though, which is a pity. He wasn't sure what he'd do with the extra time. I, of course suggested fighting crime. He said that that sounded like a good idea, and went off to get a muffin.
