LSU Medical School students were receiving their first anatomy class
with a real dead human body. They were all gathered around the surgery
table with the body covered with a white sheet. The professor started the class
by telling them "In medicine, it is necessary to have two important
qualities as a doctor - the first is that it is necessary that you not be
disgusted."

The professor uncovered the body, stuck his finger in the butt of
the dead body, withdrew it and sucked his finger.

"Go ahead and do the same thing." He told his students.

The students freaked out, hesitated and subsequently took turns sucking their finger after withdrawing it from the rectum.

When everybody was finished, the professor looked at them and told
them "The second important quality is observation. I stuck my middle
finger in and sucked my index finger. Pay attention people!!!!!"
