In school, we had a teacher who as famous for making jokes at the expense of others. One time during chemistry in front of the class he said to his most-liked pupil: "We have enough poison here to kill everyone in class. Well, except me and you, of course." And that was the time the class decided to go to our head teacher and tell her that his jokes were not funny at all and she reported back that our chemistry teacher was surprised about how someone did not appreciate his brand of humor.
