Here's an old riddle: A boy and his father are in a car crash and the father is killed instantly. The boy is airlifted to the best hospital in the region and prepped for emergency surgery by one of the top surgeons in the country. The surgeon rushes in, sees the boy, and says "I can't operate on this patient. He's my son." Who is the surgeon?
When I heard this riddle as a teenager back in 1962, I was totally stumped. Had the boy been adopted, and the surgeon was the birth father?
