Once upon a time in a court
Judge : Doctor, before your performed the autopsy, did you check for a pulse?
Doctor : No
Judge : Did you check for blood pressure?
Doctor : No
Judge : Did you check for breathing?
Doctor : No
Judge : so, then it is possible that the patient was alive when you began the autopsy?
Doctor : No
Judge : How can you be so sure, Doctor?
Doctor : Because his brain was sitting on my desk in a jar.
Judge : But could the patient have still been alive nevertheless?
Doctor : Yeah, It is possible that he could have been alive and practicing law somewhere.
