The Boy Scout
A noted brain surgeon, Dr. Bronson Ray, was taking a stroll when he saw a boy on a scooter smash headfirst into a tree. Realizing that the boy was seriously injured, the doctor told a bystander to call an ambulance.
As he proceeded to administer first aid, a boy not much older than the injured one, nudged through the crowd that had gathered and said to Dr. Ray, "I’d better take over now, sir. I’m a Boy Scout, and I know first aid."
