I don't know about you, but when I was in school, I doodled a lot during class. I don't remember ever defacing school property by doodling on the desks, but I could have repressed those memories, remembering myself only as a straight-A student who just didn't DO those kinds of things. Ha! Here are some interesting examples of desk graffiti I found online. Most appear to be from the '90s or later, and the spelling errors in a few of them prove that the "artists" probably should have been paying attention in class!
