Dr. Omar was called to give expert evidence in a recent court case.
Lawyer: Dr. Omar, before you performed the autopsy, did you check for a pulse?
Lawyer: Did you check for blood pressure?
Lawyer: Did you check for breathing?
Lawyer: Aha! So, then it is possible that the patient was alive when you began the autopsy?
Lawyer: How can you be so sure, Doctor?
Omar: Because his brain was sitting in a jar on my desk.
Lawyer: But could the patient have still been alive nevertheless?
Omar: It is possible. If so, he would be alive and practising law somewhere.
