Concentration Test :)

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's ass & 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's ass & 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..:P
