I've had my fair share of interesting professors in my college days. I remember one professor walking into class on the first day and telling us that he had tenure, so there was nothing we could do to get him fired. Which was basically his way of saying that this was his class and we were going to have to do things his way if we wanted to pass. That was one way to get our attention, and as narcissistic as it might seem on his part, it worked.
In this case, it looks like the professor lost his mind a little, as well as control of the classroom. You've got to be a leader if you want people to follow you, and it doesn't seem like this professor did a very good job of taking and maintaining control.
A professor at Texas A&M Galveston failed his entire class for systematic disrespect and because he believed that the class simply couldn't do the work. However, from the information in the video below, it doesn't sound like the semester was even over yet... Don't you have to finish the course to know if you've failed or not?
This nutty professor had a breakdown. I'm not sure what happened in the class or what was going on for him personally, but everything about this situation seems to be handled poorly on the both the part of the professor and the class.
