Pay attention

1st yr MBBS students were attending their 1st anatomy class. They all gathered around the table with real dead body. The professor started the class by telling them two important qualities as a doctor. The 1st is that never be disgusted about anything regarding the body e.g. he inserted his finger in the body nose & on drawing back, put the finger in his own mouth & tasted it. Then he told the students to do the same. The students hesitated for several minutes, but eventually everyone inserted their fingers in the body nose & tasted it. When everyone finished the professor looked at them & said :The most important 2nd quality is Observation. I inserted my middle finger but tasted the index finger. Now learn to pay attention All students : shitttt !!
