I was taking graduate comp sci classes to meet a job requirement.

The professor was a retired manager from Bell Labs (where I was working). She taught using Pascal as the examples, but told us if we didn’t know Pascal we could write and compile the assignments in whatever language we were familiar with.

She graded one of my exams and took of points for a couple of lines because they weren’t valid Pascal (I was doing most of my programming in C and what I did was valid using C). I went to complain since the course requirements didn’t specify knowledge of Pascal.

She refused to change the grade (a 97%) because it wasn’t valid Pascal.

When our major assignment was due, I wrote it in C (we just had to provide the source code and compiled output). Actually, it was C but the most obscure and convoluted C I could create (and it created the desired output quickly). But if you weren’t an expert in C, what I wrote would be incomprehensible. Have you ever seen 20 conditionals in one statement (LOL).

She couldn’t understand my code and so approached the other instructors for advice. They, of course, immediately recognized what I had done and openly laughed at the professor after looking at the code.

Got a A and the instructor ending up resigning because the other instructors so enjoyed the joke.
