Learning, Listening, oops

I can’t PG rate these, they’re said by kids *shrug*

The 4th grade science teacher, Mrs. Parks, asked her class, “Which human body part increases to ten times its size when stimulated?”

No one answered until little Mary stood up and said, “You should not be asking fourth-graders a question like that! I’m sooo going to tell my parents, and they will go and tell the principal, who will then fire you!”

Mrs. Parks ignored her and asked the question again, “Which body part increases to 10 times its size when stimulated?”

Little Mary’s mouth fell open. Then she said to those around her, “Boy, is she going to get in big trouble!”

The teacher continued to ignore her and said to the class,”Anybody?”

Finally, Billy stood up, looked around nervously, and said, “The body part that increases 10 times its size when stimulated is the pupil of the eye.”

Mrs. Parks said, “Very good, Billy,” then turned to Mary and continued. “As for you, young lady, I have three things to say: One, you have a dirty mind. Two, you didn’t read your homework. And three, one day you are going to be very, very disappointed.”

Then it gets worse…

Little boy was doing his maths homework.
He said to himself,
“Two plus five, the son of a b!tch is seven.
Three plus six, the son of a b!tch is nine…”
His mother heard what he was saying and gasped, “What are you doing?”
The little boy answered, “I’m doing my maths homework, Mom.”
“And this is how your teacher taught you to do it?” the mother asked.
“Yes,” he answered.
Infuriated, the mother asked the teacher the next day, “What are you teaching my son in maths?”
The teacher replied, “Right now, we are learning addition.”
The mother asked, “And are you teaching them to say two plus two, the son of a b!tch is four?”
After the teacher stopped laughing, she answered, “What I taught them was, two plus two, THE SUM OF WHICH, is four.”
