Remember back in high school when you’d opened up your textbook to find George Washington picking his nose and Joseph Stalin with a peg leg and eye patch. It was enough to make you bow down and thank the graffiti gods for giving you a much needed distraction from the incessant ramblings of your instructor.

Textbook doodles seem to transcend national borders and bored students from all over the world appear to have a penchant for defiling educational tools. We’ve already shown you some from Asia, a continent that seems to be home to an abundance of bored students with idle hands. Now let’s take a look at textbook doodles from Twitter user and Japanese high school student, Chanta, who takes it to a whole other level, actually erasing parts of his textbook to create entirely different, albeit twisted, pictures.

First, here’s a smattering of before and after shots of Chanta’s textbook.
