Irrelevant, but mildly diverting
This stout fella, in an attempt to trap the ball, accordingly ducked his head sharply and, with quite astonishing force, smacked his face into the desk. The thud echoed through the building and our budding economist remained slumped over his desk for a little while as his considerate classmates fought unsuccessfully to control their hysterics. After a minute or so he raised a head that now had a large red bruise stamped in the middle of his forehead, thus proving he was at least alive. In partial compensation for semi-concussing himself, he was allowed to take the rest of the lesson off, albeit to go to the San to be checked for permanent damage.
This all goes to show something, though I'm sure I don't know what.
