a fwd i got from a classmate....

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. 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
