Many a student has drawn animals -- or other funny cartoon scenarios -- on a test they were destined to fail, either in hopes of getting a few bonus points for LOLs, or because they knew it was already game over and figured they might as well go for broke.

But what you don't often see is a teacher (math, no less) who not only answers back with their own cartoon, but uses it to own the student in an impromptu Pokemon battle right there on the exam. Charizard fainted, indeed.
