The medical students receive their first course of anatomy with a real human body.
They all gathered around an operating table with a body covered with a white sheet
The professor say:
"In medicine, we must have two important qualities.
The first one is to not be disgusted.
Then the teacher removes the sheet, presses a finger into the anus of the dead body and,
he sucks his finger.
Ok, Now do the same thing.
After a few minutes of hesitation the students move in turn.
They sink a finger into the anus of the dead body and suck their fingers.
When everyone finished the teacher looks at them and say:
The second quality is observation.
I pressed my middle finger and I sucked the index
