Student: My math exam conflicts with this class's exam.
Me: Hmm, that's weird. That's not what the exam schedule says. Let me check with your professor. What's your math professor's name?
Student: Kim Jong Un

I emailed him and it's true. The math professor's name coincidentally IS exactly the same as the North Korean dictator's. One of the unexpected joys of working at a Korean university.

AND the student was right: the exam schedule is wrong :(
