The sixth grade teacher, Mrs Wallan, asked her class,
"Which part of the human body can grow to ten times it's
norman size when stimulated?"
No one answered until little Mary stood and said, "You
should not be asking a question like that. I'm going to
tell my parents and you will get into trouble."
Mrs Wallen ignored her and asked the question again,
"Which part of the body increases in size when stimulated?"
Little Mary's mouth fell open. Then she said to those around
her, "Boy, is she going to get into trouble!"
Finally, John put up his hand and said, "Please Miss, it's the
pupil of the eye."
Mrs Wallen said, "Thank you John." She turned to Mary and
said, "As for you young lady, I have three things to say to
you. One - you have a dirty mind. Two - you haven't read your
homework and three, one day, you are going to be very, very
disappointed!"
