A Lesson To Be Learned
The day after giving her class 3 chapters to read for their homework
the 8th grade science teacher, Mrs. Parks, asked her class "Which human
body part increases to 7 times its normal size when stimulated?"
No one answered until little Mary stood up, angry, and said, "You should
be asking 8th graders a question like that! I'm going to tell my parents,
and they will go and tell the principal, who will then fire you!"
With a sneer on her face, she then sat back down.
Mrs. Parks ignored her and asked the question again, "Which body part
increases to 7 times its normal size when stimulated?"
Little Mary's mouth fell open; then she said to those around her," Boy, is
she gonna get in big trouble!"
The teacher continued to ignore her and said to the class, "Anybody?"
Finally, Kevin stood up, looked around nervously, and said, "The body part
that increases 7 times its size when stimulated is the pupil of the eye.
Mrs. Parks said, "Very good, Kevin," then turned to Mary and continued, "As
for you, young lady, I have three things to say:
(1) you have a dirty mind,
(2) you didn't read your homework......and
(3) one day you are going to be very, very disappointed."
