The 6th grade science teacher, Mrs. Parks, asked her class, “Can anyone tell me which human body part increases to ten times its size when stimulated?No one answered, so the teacher pointed at a student at random.

Little Mary protests the dirty question

Little Mary stood up, crossed her arms and said, “You should not be asking sixth graders dirty questions like that! I’m going to tell my parents, and they will go and tell the principal, and then he’ll fire you!”

Mrs. Parks ignored her and asked the question again, “Let’s try that again. Which body part increases to 10 times its size when stimulated?”Little Mary’s mouth fell open. She pointed at her teacher and yelled, “You’re gonna 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 smiled and said, “Very good, Billy,”She 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.”
