When one is a professor, one rarely has spare time. Other non-professor types may believe that they have lots of spare time in which they just sit and think (and mistake for busywork) but the truth is, when one teaches a large group of college students, on rarely has free time. And so it was that Professor Richard C. Halbernager (pronounced:Hall-bur-nager, which he is extremely particular about) found himself alone in his office late at night, grading essays which he now wondered why he had assigned.
When one is a demonic nightmare-bringer, one usually does not exist. But if one did exist, one would assume that he would be busy, most likely bringing nightmares in a demonic fashion. This, actually, is the truth but does not explain why a small one was now winging its way towards the office of Professor Richard C. Halbernager. As Professor Halbernager was not asleep, it seemed that it would be rather difficult to bring him nightmares. However, this was an ambitious (if not that intelligent) demonic nightmare-bringer; and he, to the disappointment, embaresment and great amusement of all higher demons, had a plan.
This may partially explain why a small demonic nightmare-bringer burst through the window of the office of Professor Richard C. Halbernager and landed on his chest.
Demonic nightmare bringers are small demons who are, as a whole, not all that intelligent. It is partially for this reason, and partially because of Newton's first law, that the aforementioned small demonic nightmare-bringer failed to remain on the good professor's chest once he struck it. It is because of this that he found himself upside down in a book case. In the company of a very stunned professor with an annoyingly long name, lying on his back in a state of shock. Needless to say, victory was not his.
