A Forensic Class

in a forensic class, the professor is taking his students for their first practical lesson. All of them were very excited and nervous at the same time.

the professor gathered the students around a dead body and said " there are two main points to be a good forensic scientist. First, one has to dare to do anything to a dead body in order to find the real cause of death"

having said that, he put his finger in the dead body's arse and put it in his mouth, and instruct all his students to do the same.

One by one, reluctantly, they each stuck their finger into the body's arse and put it in their mouth.

after the last student had finished doing so, the the professor continued " the second point to be a good forensic scientist is to b observant, notice that i had put my index finger into the arse but put my middle finger into my mouth"
