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 her 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."
