You have to chill out and be cool when you meet your class come September. This teacher wanted to make a good first impression on his class. One that would show that he was the cool teacher in the school. That said, he did the nerdiest thing possible and showed up as a knight from the medieval times. We’re hoping the class didn’t mock him too much. It would be a total drag if this was the last time he ever tried to pull off this gag.
