Mr. Cikoch was a biology instructor at a snobby suburban girl's junior
college. During class one day he asked his student, "Miss Simison, 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 Simison gasped, and then said, "Mr. Cikoch, 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.

Mr. Cikoch then called on Miss Hakar and asked the same question. Miss
Hakar, with composure, replied, "The pupil of the eye, in dim light."

"Correct," said Mr. Cikoch. "And now, Miss Simison, 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."

well done ......lol...

that sounds like something a teacher would actually say
