Real stories from the front (and not from Duke, by the way):
American politics class. Students studying for exam. Two nights before the exam, prof receives following email:
"We were studying for the test, and came up with this question for you. Do we have to know the order in which the Federalist papers were written? And, if so, how can we find that out?"
My advice: If you get an email like this, go for a walk. Don't answer it right away.
