During a 6th-grade science lesson, the teacher posed a simple question to her class: “Which human body part increases to ten times its size when stimulated?”
The class remained silent, until Mary, one of the students, stood up and voiced her disapproval. “You shouldn’t be asking sixth-graders a question like that! I’ll tell my parents, and they’ll tell the principal, who will fire you!”
Ignoring Mary’s outburst, Mrs. Parks repeated her question, emphasizing the scientific nature of it. “Which body part increases to 10 times its size when stimulated?”
Mary’s shock was evident as she turned to her classmates. “She’s going to get in big trouble for this!”
Still unfazed, Mrs. Parks looked around the classroom, patiently waiting. “Anyone know the answer?” she asked once more.
After a moment, Billy nervously stood up. He glanced around before answering, “The body part that increases ten times its size when stimulated is the pupil of the eye.”
Pleased with his response, Mrs. Parks congratulated Billy. She then turned to Mary and added, “As for you, young lady, I have three things to say: First, you have a dirty mind. Second, you didn’t do your homework. And third, one day, you’re going to be very, very disappointed.”
