There is an amusing letter from a teacher that has been circulating the net for a few years. It is described here:
That is the set-up in the letter displayed above, putatively written by a teacher (Adam Hilliker) to the mother of one of his students, notifying the parent that her son (Alex) will be serving one hour's detention for "disregarding authority" and demonstrating a "complete lack of respect for his school." The student's transgression? Having corrected a teacher who insisted to his class that a kilometer was longer than a mile. (In fact, a kilometer is only about 62% of a mile.) AlthoughI am inclined to think that no teacher is this stupid, and that the letter is fake. The truly stupid professionals are in other occupations.
Mr. Hillikeracknowledges that the student was indeed correct, he maintains that young Alex "would be better off simply accepting my teachings without resistance."
