Microeconomics professor @ college and another one on other class, can't remember which one.
We were the unfortunate group to see such a questionable intelligence on the MicroEco professor. He had like, 10 credit cards and still had credit problems... Do what I say but do not do what I do? (A famous brazilian phrase...)
We had a test, near the end of the semester that had two questions with VERY similar topics and answers. One of them had two ambiguous and right questions. When he corrected the test he said that one question is MORE RIGHT than other one... After 4 months of abuse, most of us flipped out.
A jerk that was in my class almost fought with him, after that the jerk went to the principal office to fill a complain about him. After we finished the semester we never saw him again.
The other one is quite a story! Sit down and listen (read).
1st week of the class, and came this guy, from São Paulo and stuff... All snobby and shit. Great speech, good presence... Okay. So I thought... "Lets search for the curriculum lattes of this guy..." (curriculum lattes is a platform to aggregate articles and research for a person. mainly used for scientists, researchers and college/PHD professors).
After I googled his name I found out that he stole money from a company in São Paulo and was responding on a process of the Receita Federal (brazilian IRS, kinda).
I was stunned. I found out everything in 5 minutes or less. And my course coordinator couldn't find it.
I told a personal friend of mine, I didn't want to talk about it with anyone, because the coordinator was new and everyone (except me and a few other people) hated her.
After a week everyone knew. Okay.
3 months later, the professor scheduled a trip to Uruguay. I didn't went, cause I had no money
But... HE DIDN'T CAME BACK. LOL
He got a job there on a cassino... WTF.
After this incident our coordinator came to my class and we discussed on what we were supposed to do...
oooh, good times.
TL;DR: one was a stupid mess of shit and another one was a big shitty bag full of lies.
