Be observant – A lesson! 0
A lecturer teaching medicine was giving a classoom observation. He took out a jar of yellow liquid. “This,” he explained, “is urine. To be a doctor, you have to be observant of color, smell, sight, and taste.”
After saying so, he dipped his finger into the jar and put it into his mouth. His class watched in amazement, most in disgust. But being the good students that they were, the jar was passed, and one by one, they dipped their finger into the jar and put it into their mouths.
