A class of First Year medical students

A class of First Year medical students were receiving their very first anatomy class with a dead human body.

As they all gathered around the surgery table with the body draped with a white sheet.

The Doctor started the class by telling them, When you practice medicine, it is essential to have two highly important qualities as a doctor. The very First thing is that you should never be disgusted by anything involving the human body.

The Doctor then pulled back the sheet, and stuck his finger in the a open wound in the corpse, withdrew it and stuck it in his mouth.

Now You interns go ahead and do the same thing. The interns initially freaked out, hesitated for many minutes, but after awhile took turns sticking a

 finger in the open wound, and started sucking on their fingers.

When everyone had finished, the Doctor looked at the class, shook his head and told them, The second most important quality is close observation.

I stuck in my middle finger in the wound, but sucked on my index finger. Now learn to pay attention!
