**First-year students at Medical 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 began the lecture by telling them: "In medicine, it
is necessary to possess two important qualities as a doctor: The first
is that you not be disgusted by anything involving the human body." **

**To illustrate, he pulled back the sheet, stuck his finger in the anus
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
sucking 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 sucked on my index finger. Now learn to pay
attention." ***
