If papers, handouts, etc have a blank side, I put them in a drawer to use for scratch paper later. Here's what was on the "blank" side of the piece of paper I just pulled out:
Based on the other side of the paper, this is from a class about language politics and planning in 2006. I have no idea what the other relevant details were that led to this being drawn.
It's much harder to draw lots of hilarious cartoons during a class now that I am usually teaching the class.
Other in-class cartoons from my more-prototypically-studential days were about theta roles, morphology, and the extremely irritating and frustratingly common belief that gorillas can learn ASL*. I still haven't gotten around to the one about Phonology + Chrononhotonthologos = Phonolohotonthologos. Yet.
*Those last two, while they began in a classroom setting, involved substantial extracurricular efforts as well.
