Speaking Of Urine
A renowned professor teaching medicine was giving a lecture. He took out a jar of yellow liquid. "This," he explained, "is urine. To be a doctor, you have to be observant of everything, especially color, smell, sight, and taste. And, never be disgusted by anything. Now, everyone, do as I do..."
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.
After the last student was done, the old professor shook his head. "I can see that you try not to be disgusted. But, if any of you had been observant, you would have noticed that I put my second finger into the jar and my third finger into my mouth, you idiots!!"
