very bad joke

For those who know me, this story is purely fictional and did not happen in real life, though my teacher really did ban anyone from drawing before class starts

So one day before class started, a teacher spotted a student drawing a picture on his sketchbook. This is what happened next.

Teacher: Take out a book to read.

Student: This is a book.

Teacher: But it's not a storybook.

Student: Don't you know that a picture tells a thousand words?

Teacher: ............
