Not a teacher, but this one made me feel bad for my philosophy professor in community college. My professor was a priest, very patient and easygoing guy, but this student really tested that. There was a woman who would sit in the FRONT row and constantly fall asleep. When she wasn't asleep she would argue with him about every major point. It was clear she was dumb as a brick, and she did it so often every time her voice piped up the whole class would collectively do that silent groan and eye roll. She was a mom and rode horses, which she brought up quite frequently. My favorite is when the professor was talking about fulfillment and motivation in jobs with high pay but with unpleasant duities. His point was that while anyone could put up with an awful job for quite a while for good money, eventually the psychological toll would become too great and you would want to quit. She objects loudly, and says if that's true how come her horse does everything she wants it to and is happy with just an apple. She literally told the professor he was wrong because her horse likes apples. The professor at this point really didn't have much of a reply, I think he finally reached his limit. Everyone in class just kind of sat flabbergasted. I tried to explain the concept of it but she just kept insisting it wasn't true because of her horse. Hands down, the worst classmate I've ever had the misfortune to have a class with. Every day was like that. Perhaps the professor thought a bit more about wether teaching was worth it after that day.
