Cursing in the classroom

I've never been more liberated than when I've been able to curse during class. Usually, that's restricted to conversations in the back of the room with friends (eg "This class is so fucking boring" or "I'd like to shit in my own hand and throw it at that ghoulish cunt of a professor") , but when you have a professor that curses, complains, and drops shit, it makes it a lot easier to answer a professor's question with "I don't like the looks of this fucking return rate, I think I'm getting shit on here," or even a simple "I'm getting a fucking IRR of 14%" said in the most casual manner possible.
