Been there done that in a ten person class in law school.
When the prick-professor surprised us at the end that we had one month to write him a 25 page paper with footnotes on one of three topics of his choice, I told him that I didn't need his one credit class to graduate.
He told me that he would have to fail me.
I told him that I could care less because I had enough credits to graduate without his class.
He told me that I would "regret it".
I told him: No I won't, I already have been hired by my first choice of law firms and have a couple of other offers to boot.
He told me that he'd be discussing my attitude with the Dean.
I told him I don't give a **** and turned my back and walked away!
So I was pulled out of another class and summoned to the Dean's office. The **** professor was already sitting there and had already argued his points.
The Dean simply asked me whether I really had told the professor: "I don't give a ****!"
Dean Abrams asked me if I really felt that way and I told him I definitely did.
Dean Abrams told the professor: "Well then Paul, there is nothing further to discus regarding this matter."
I told the Dean: "Yes there is. We had a pop-quiz in class one day that if you passed, you got a 1/2 letter grade boost on your final grade in the class. I passed that test and have earned a one-half letter grade boost. Therefore, he cannot fail me. He must give me a "D".
The professor completely lost his **** and began yelling at me. The dean interrupted him and told me that I could leave. I listened to them argue loudly for about 30 seconds, then started laughing so hard that I had to leave because they would hear me.
I saw the Dean in the hallway about a week later and he told me not to worry, he would make sure I got my "victory D". He went on to say: "Paul Joseph is an **** and you have always been one of my favorite students in your class based on all that you have done for the school (law review, moot court regional competitor, honor court prosecutor, alumni fundraiser AND THE BEST BARBRI SALESPERSON HE HAD EVER SEEN!). It's no secret around here that I don't care for Professor Joseph. Thank you for standing up to him and letting me make him lose his cool. He's up for tenure and I have already documented his file with his treatment of you. Your going to make a fine Nova Lawyer!"
I said: "Thank you very much Dean Abrahms" and walked on towards class."
The real beauty of the whole thing at the time is that I was stoned out of my mind 24/7 that entire semester when in all classes and even in the Dean's Office that one day!
Paul Joseph still got tenure, but died of throat cancer about five years later. I could have cared less...
