Student: We don't have a single Underwater Foil Hat Making course in this department.
Me: That's because we're an Underwater Basketweaving department.
Student: You should offer a degree in UFHM.
Me: If you want to study UFHM, you have to go to a school that offers it. We simply don't have the foil resources, and we basketweavers don't have training in foil work.
So it wasn't quite like that, but you get the idea.
Sometimes I get a little frustrated.
I can never remember without looking it up if Charles Brandon was Duke of Suffolk or Sussex. I need a mnemonic! (It was Suffolk. I just looked it up. But it will be gone the next time I need it.)
