Professor Passive Aggressively Quits

A couple of days ago my friend informed me of a bizarre set of circumstances: One of her friends was in a class where a professor just suddenly quit his own class. The emails of his final days are pretty hilarious, and are below. I have taken out proper names for confidentiality reasons.

Professor 1st Email:
I have extricated myself from teaching your class. You will have a new Instructor starting Monday.
All the best,
Professor

2nd Email:
There is no need for any one of you to contact me any more. Direct all your concerns to those in charge. Personally, I don’t give rat’s ass about ignorant idiots with a grotesque and overarching sense of self importance. It’s pathetic.

3rd Email:
Given the class, I can understand how “do not contact me” can be incomprehensible. So here its is in Swahili, I will grade the last test if and when I feel like it- like when I need some humor in my life (highly unlikely). Hope that answers all questions.
