The anatomy professor says, “Now, class, I’ve a few questions for you about the homework.
Miss Murphy! Stand please.” [She stands.]
“What organ expands to ten times its normal size when excited?”
Miss Murphy flushes and fidgets.
Finally the professor tells her to be seated.
“Mister Campbell: stand please and answer the same question.”
“It’s the pupil of the eye, sir.”
“Very good, Mister Campbell.
Miss Murphy, I have three things to say to you.
First, you haven’t done your homework. Second, you have a dirty mind. Third, your in for a *big* disappointment.”
