Little Johnny drew a fly on the class grade book.

It
looked so realistic, that when Miss Baker saw the fly
sitting on the notebook, she slammed it with a ruler.

The fly didn't fly away.

So she slammed the book once
again, again the fly didn't fly away.

This drove Miss Baker really mad, so she started to
pound the book with the ruler and, as a result, the
grade book became a bunch of torn sheets of paper.

With the class laughing, she realized what had
happened.

Then Miss Baker called Little Johnny's
father to school.

"You see what your son did to our class grade book?"
she said.

"That's nothing." replied the father. "Last month,
he drew a naked woman on a fence and for two weeks
straight I was pulling splinters out of my dick."
