[Mr.Fixit]

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 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
itin 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 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."
