My flippant response was possibly driven by the fact that I am always freshly surprised to find out that there actually
might be students taking one of my courses with an eye towards their GPA (clearly, ASU student corporate memory/social networking
isn't all that it is cracked up to be :-).
Thinking about it again, I can imagine some students being unduly inconvenienced by having to keep up with an extra meeting that they haven't bargained for, in the last week of classes.
So, I will certify that the material covered in tomorrow's lecture will not be "on the test".
