When I was a university student, I found a book which taught you how to insult people in Latin. So, I sometimes inserted insulting Latin phrases into research papers I wrote, just to see if any of my 'smarter-than-thou' profs would catch on. None of them ever did! Of course, I only did this to profs I considered over-rated charlatans.
I had a teacher in seventh grade who would tell you the answer to any test question in Hungarian, several one the kids learned enough to get higher grades.
@Agnieszka Some of the kids were quite smart and had nothing else to do. North Central Montana 40 miles from the Canadian Border. One has to drive past Nowhere to get there.
