Biology

BIOLOGY professor Mr White asked one of the girls in his class: "Miss Smith, would you name the organ in the human body, which under the appropriate conditions, expands to six times it's normal size, and define the conditions."

Miss Smith gasped, then said snottily: "Mr White, I don't think that is a proper question to ask me.

"I assure you that my parents will hear of this."

With that, she sat down red-faced. Unperturbed, Mr White asked Miss Jones the same question.

She replied: "The pupil of the eye, in dim light."

"Correct," said Mr White. "Now, Miss Smith, I have three things to say to you: one, you have not studied your lessons. Two, you have a dirty mind. And three, you will someday be faced with a dreadful disappointment."
