LESSON ON OBSERVATION
lecturer teaching medicine was tutoring a class on 'Observation'.
He took out a jar of yellow-colored liquid. "This",
he explained, "is urine. To be a doctor, you have to
be observant to color, smell, sight, and taste."
After saying this, he dipped his finger into the jar and
put it into his mouth. His class watched on in amazement,
most, in disgust. But being the good students that they
were, the jar was passed, and one by one, they dipped one
finger into the jar and then put it into their mouth.
After the last student was done, the lecturer shook his
head. "If any of you had been observant, you would
have noticed that I put my 2nd finger into the jar and my
3rd finger into my mouth."
