Miss Smythe
Mr. Perkins, the biology instructor at a posh suburban girl's junior
college, said during class, "Miss Smythe, would you please name
the organ of the human body, which under the appropriate conditions,
expands to six times its normal size, and define the conditions."
Miss Smythe gasped, then said freezingly, "Mr. Perkins, I don't think
that is a proper question to ask me. I assure you my parents will hear
of this." With that she sat down red-faced.
Unperturbed, Mr. Perkins called on Miss Johnson and asked the same
question. Miss Johnson, with composure, replied, "The pupil of
the eye, in dim light."
"Correct," said Mr. Perkins. "And now, Miss Smythe, I have three
things to say to you. One, you have not studied your lesson. Two,
you have a dirty mind. And three, you will some day be faced with a
dreadful disappointment."
