First-year students at Med School were receiving
their first Anatomy class with a real dead human
body. They 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 2 important
qualities as a doctor. The first is that you not
be disgusted by anything involving the human body."

For an example, the Professor pulled back the
sheet, stuck his finger in the butt of the corpse,
withdrew it and stuck his finger in his mouth.

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

The students freaked out, hesitated for several
minutes, but eventually took turns sticking a
finger in the butt of the dead body and sucking on it.
Each one tried his best not to puke.

When everyone had finished, the Professor looked
at them and told them, "The second most important
quality is observation. I stuck in my Middle
finger and sucked on my Index finger. Now learn
to pay attention."
