Accept no substitutes!
I am in the midst of grading exam papers. As a math teacher, I appreciate that I have an easier job of it than my colleagues in most other departments. Professors of English composition tell me that grading term papers is an extremely time-consuming endeavor. Colleagues in political science frequently encounter the full panoply of logical fallacies while reading their students' essays. By comparison, I seem to have the more straightforward task.
This is entirely reasonable, of course, since I'm a math teacher. We deal in unambiguous Truth and its handmaidens, Right and Wrong (with an occasional visit from the perky sidekicks, Clueless and Ludicrous).
I came across this cartoon at Stoat, where William thanks Hank for the tip. Naturally, I thank him, too.
