Mixing funny one-liners with pictures from a literature textbook, one student (who definitely wasn’t paying attention in class) came up with some pretty hilarious snaps to send to his friends on the photo messaging app. Luckily, Imgur user MycketKreativtNamn uploaded screenshots so the rest of the world could share in the fun.

In 2013, a Tumblr user posted similar snaps from a physics textbook proving that any subject is fair game when it comes to some Snapchat entertainment.

Teachers, you’ve been warned.
