Medical Experiment

First year UNILAG medical students were attending their very first anatomy class. They all gathered around the table which had a real dead body on it. The Professor, Mr. Akpos, started the class by telling them two important qualities of a doctor. "The first is that never be disgusted about anything in the body. For example",

He inserted his finger in the dead body's anus, put his finger in his own mouth and tasted it. Then he told the students to do what he did. The students hesitated for several minutes, but eventually everyone inserted their fingers in the body's anus and tasted it.

When everyone finished tasting their fingers, the professor looked at them and said, "The most important Second quality is Observation. I inserted my MIDDLE finger but tasted my other finger. Now learn to pay attention!!"

One word for Professor Akpos?
