    When I was in elementary, my teacher said that “Lutetia” was how the Romans called the city of Liege. As an avid reader of Asterix comics, I knew this isn’t true and corrected her and said it was the Roman name of Paris. She insisted that it is Liege. Anyway, the next day, she came back to class and said that she looked it up and that I was indeed correct and Lutetia referred to Paris and gave me a chocolate bar and told me to keep reading comics. Good teacher.

      In elementary school our teacher asked us to spell the current year with roman numerals, so I worked out “MCMXCVIII”, which I was quite proud of. But the teacher came back at me quite snarkyly and said it’s much easier to just substract 2 from 2000, “IIMM” duh!

      It was only many years later that I accidently learned that he was indeed full of shit and I was right all along.

        it’s much easier to just substract 2 from 2000, “IIMM” duh!

        For anyone wondering why this is wrong, there are two reasons:

        1. The roman numeral system only traditionally contains subtractions from the next higher five- and tenfold symbol. So you can subtract I from V and X, X from L and C, C from D and M

        2. The subtractions only generally allowed one symbol to be subtracted, with a few notable exceptions like XIIX for 18 and XXIIX for 28

          Holy shit this is dope!

          But how did historians come up with the conclusion that, in the case of XIIX, the Romans substracted from the second X, and didn’t just write 12+10?

          Not arguing, just extremely curious

            The general rule is that the larger symbols come first in Roman numerals, so 12+10 (22) would be written as 10+10+1+1 or XXII.

            If you literally meant the arithmetic 12+10, I’d assume they used some symbol for addition, so it would be written as XII+X, but I can’t say for sure.

          I’m pretty sure people would have caught on to pretending it was two years in the future :)

      I had a HS teacher say the the 2nd to 5th richest people were the Walton(of Walmart) family heirs. I knew this wasn’t right because at the time, Steve Balmer(of Microsoft) was the 5th or something. I printed out the Forbes list and brought it in. The teacher coped by saying that if you combined the Walton wealth, it would rank that high. He was a POS teacher for more significant reasons than that though.

        I once got in trouble with my math teacher for saying “well if we’re just making things up, then sure [I cheated on a math test while sitting in the front of class where the teacher can see but I was using some kind of hidden code on my t-shirt that was a bunch of Shakespearean insults] . But what about all that Crack you were doing in your car this morning?”

        Apparently my "making things up"was a slightly more serious than his. I stand by it. If we’re making shit up, we’re making shit up.

        For the record, this geometry teacher was convinced I was cheating in class because I didn’t do homework. Homework was 5% of the final grade for the year according to his syllabus, I hated homework, so I figured as long as I didn’t suck at the rest of the class, I could do 0 homework and pass. I was right, passed with a 94%

      In my country, the written final exams include a Q&A section in the beginning of the test, where the teacher and the headmaster are present, and where they present the tasks and students are allowed to ask questions. After that section, the headmaster leaves and students and teachers aren’t allowed to talk for the rest of the test.

      I noticed a missing specification in one of the tasks. It was a 3D geometry task, and it was missing one angle, thus allowing for infinite correct results. During the Q&A section I asked about that, and my teacher looked sternly past me to the end of the room and said “I am sure the specifications are correct”. If there was an actual error in the specifications, the whole test would have been voided and would have to be repeated at a later date, for all the students attending.

      As soon as the headmaster was out of the room, he came to me and asked where he made the mistake. He then wrote a fitting spec on the whiteboard.

      I liked that guy. He was a good teacher.
