The original riddle goes something like this > A father and son were in a car accident where the father was killed. The ambulance brought the son to the hospital. He needed immediate surgery. In the operating room, a doctor came in and looked at the little boy and said I can't operate on him he is my son. Who is the doctor? The riddle is literally just a play on "women can't be surgeons."
