Mrs. Parks asked her students a funny joke.

Mrs. Parks, a 6th-grade science teacher, asked her attentive students, “Can anyone enlighten me about which specific component of the human body undergoes a remarkable tenfold increase in size when subjected to stimulation?”

A quiet descended on the classroom, with no instant comments forthcoming, until a strong voice rose from the audience. Young Mary was the one who chose to take a stand, not just against the question but also against the propriety of such a subject for her fellow sixth-graders.

“I firmly believe that questions of this nature are inappropriate for people our age!” she remarked. I will not remain silent; I intend to alert my parents, who will escalate the situation to the esteemed principal, who will undoubtedly consider dismissing you!”

Mrs. Parks remained unfazed, questioning with tenacity, “Can anyone elucidate the body part that demonstrates a tenfold expansion in size when subjected to external stimuli?”

Mary’s face was flushed with surprise, her mouth falling open in amazement. “My, oh my, the repercussions for this are going to be monumental!” she mumbled to her peers.

Mrs. Parks remained undeterred by the uproar, addressing the class with eagerness, “Who among you can unravel this intriguing mystery?”

Billy, a bashful figure, rose from his seat after a few pauses, his uneasy looks darting about the room. He added, a little hesitantly, “The body part that responds with a tenfold increase in size when prompted is the remarkable pupil of the eye.”

Mrs. Parks expressed her appreciation for Billy’s intelligent comment, nodding appreciatively. “Excellent, Billy,” Mrs. Parks replied, turning to Mary and continuing.

“As for you, young woman, I have three words for you: one, you have a filthy mind. Two, you still need to complete your homework. And three, you will be very, very dissatisfied one day.”
