Looking back it was so funny how high school teachers would pull the "you won't be able to get away with stuff like this in college, your professors expect you to be serious" or any hint that college is a Deeply Serious place.
One year in college I took a summer class on The Canterbury Tales because the super rad professor from my "Saints, Whores, and Warriors: Women of Medieval Europe" class was teaching it and convinced me that learning all the dirty jokes in Chaucer would be a rad way to spend the summer (she was correct).
Anyway, the university assigned us a modular classroom, or a trailer, and she was pissed. It was summer semester, you really couldn't find one classroom on this whole campus for 15 freaks reading Chaucer? Really? So she decided to move the class to the little 1890s house on the other side of campus where the English department was and we could enjoy the nice former living room/dining room for the summer.
She leads us on our trek across campus, not really paying attention to us. We file inside and get seats around the table as she is unpacking her bag and getting set up. Finally she turns around to see all 15 of us eating one of these
"What the...fuck? How? Where did you all get popsicles?" Total bewilderment.
Someone explained that the GRE test prep people where handing them out to students. Her reaction was "well this is unacceptable." And she went and demanded one of her own and we all enjoyed a frozen treat as we discussed the finer point of the Knight's Tale in middle English.
Not to be confused with the time a kid showed up like 20? 30? minutes late for a different English class with the excuse "sorry, there is a bouncy castle outside and I lost track of time" to which the professor responded "There is a bounce house?! Class dismissed." and just fucking left.
Summer classes have a real wild energy because no one is on campus and also the actual classes last longer.
My “biology for non majors” summer class, or hey kids this fulfills a credit requirement to graduate, class was 3 hours per lecture (twice a week) plus the weekly lab.
One week we got maybe 90 minutes into a class and the professor let out this long groan “this just keeps going doesn’t it? My god, I’m so bored! Are you bored? Don’t answer. Everyone go take a 30 minute break” they were a good teacher and the class was super interesting but also they were correct. That class also had a quiz that was a biology crossword puzzle, we were allowed to work on it in groups.
Or my American History through fiction class (or let’s learn labor history through novels) when the professor showed up first day in full costume as a mine worker and proceeded to tell his story of life in a mining town.
