"Wallace"

In my Greek class our text book is an advanced Greek grammar written by a man by the name of Wallace. Thus, we affectionately refer to the book siply as "Wallace," because, Greek Grammar, Beyond the Basics doesn't roll quite so smoothly off the tongue.
Anyway, Wallace concludes his chapter dealing with the several uses of the Nominative Case (I'm not going to explain it to you), with this final entry:

V. Nominative ad Nauseum

Also known as the aporetic nominative (from the Greek aporew, "I am at a loss"), this is the category one should appeal to when another slot cannot be found. The title is descriptive not of the nominative but of the feeling one has in the pit of his/her stomach for having spent so much time on this case and coming up with nothing.

I must admit, I wasn't sure that Wallace was capable of telling a joke. Isn't that a rule? Authors of Greek Grammars have to be dull and unhumorous. Well, it makes me respect the book a little more, and makes me a little more excited to read it. Maybe there's a couple other jokes in there!
