A while back, we wrote a post about clever kids who used humor to sarcastically answer their exams. Now, a teacher has come out to prove that teachers can certainly outwit their students. Squeezymo, an Imgur user who happens to be a quirky science teacher, shows us how he gets back at his students’ doodles in hilariously awesome ways. He noticed how often his students doodle on their test papers using pencils, so he started adding to the doodles using his red pen and creates a whole new story out of it. Check out some of the student-teacher doodle wars through the following pictures and head on to his Tumblr account for more.
