Presumably, the class was not "How To Use Spaces Between Words."

This is the stuff that both students' and teachers' nightmares are made of. Actually, everyone has that nightmare about realizing during finals week that you'd signed up for a class at the beginning of the semester and forgotten all about it — but at least in that dream, you're the only one who is failing. You don't take the whole class down with you and cause your professor to give up on the career they spent most of their lives getting a PhD for. We don't know what this subject is, but we recommend it be placed in a box and stored away in the warehouse from the end of Raiders of the Last Ark with all the other dangerous things that will destroy anyone who looks upon them.
