Pay Attention

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 two 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 it 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 licking
on it.

When everyone finished, the Professor looked at them and said, "The
second most important quality is observation. I stuck in my middle
finger and licked on my index finger..... now learn to pay
attention...".
