For my first teaching assignment as an assistant professor at a big public university, as is common practice of professorial hazing by tenured faculty against new hires, I was assigned to teach an introductory logic class to "student afweets." It was my first experience attempting to convey the beautiful, harmonious principles of human logic to a class that was 40% filled with dirty niggers. Day 1: I start with the basics of conditional logic. You know, with two propositions p, q and the formula p-->q means p implies q. If p then q. I write on the board, "p-->q" and say to the class, "if p, then q. p occurs therefore...." at which point a human student says, "q." I then write on the board, "a-->b" and say to the class, "if a then b. a occurs, therefore..." at which point one of the smelly, dirty niggers blurts out, "q." The remaining 60% of the class, all human, myself included, erupt in raucous laughter for what seemed like minutes. I shook my head, still laughing with tears in my eyes, turned around, sighed and muttered under my breath, "niggers." The next semester, instead of waiting for a teaching assignment, I volunteered to lead an elite "special topics" theoretical seminar for 3rd year Ph.D. students in the department and never had this problem again.
