Arrogant teacher confronts entitled student who boasts of his superior knowledge, making him look like a fool in front of entire class

In this world, there are two kinds of people: those who get their kicks from being the teacher's favorite and those who could care less about how they appear in the classroom.

The story below is of a frustrated employee. The original poster (OP) was required to attend a training session with his colleagues. Even though OP had already completed a course that was identical to what his bosses mandated, he nevertheless eagerly participated. That being said, despite his regular attendance, he made an effort to avoid being overly involved because he was familiar with the course subject and didn't want to spoil it for his eager coworkers. Despite OP's best efforts, his instructor wasn't convinced and advised him to change his conduct or risk failing the class. So, in a moment of inspiration, OP came up with a brilliant plan to teach the instructor a lesson she would never forget.

That being said, be sure to read the story below if you're interested in learning what happened next! After you're done, don't forget to read the account of the underpaid worker who was humiliated by her micromanaging supervisor for consistently showing up to work in the same outfit!
