Dirty Mind:

It was Professor Smith's first day at St. Johns Medical College as a faculty.

Known for his teaching excellence, he made his entry into a classroom of 1st year medical students, where he received a warm welcome from the students, followed by their intro.

To start with, he planned to put forth a question to the class.

He said,"Well students, before we start off with today's lecture, let me ask you a simple question on human anatomy".

He gazed across the classroom, spotted a female student Suzie, and said, "Tell me Suzie, which part of the human body grows 10 times its original size when excited?"

Hearing this question, Suzie's face grew pale in embarrassment, she replied,"You should be ashamed to ask such a question to a female. I am sorry, but I can't answer your, this question".
Thwarted by the girl's reply, Professor Smith looked around the classroom afresh, to find out if there was anyone else who could satisfy his query.

This time he located a male student Henry, who had already raised his hand in affirmation to answer the question, and allowed the lad to go ahead.

Henry answered,"Pupil of a human eye."

The professor applauded for the boy's accurate answer; then turned back to Suzie and said,
"Look, Suzie, I am sorry but, I must tell you a few things:
(1) You lack knowledge
(2) You have a dirty mind and
(3) Your Expectations are too high !!!!!!!
