Someone actually impersonated a doctor and almost got away with it.

"During the Korean War Ferdinand Demara impersonated a doctor on a Royal Canadian Navy Destroyer. When several Korean combat casualties were brought on board, the responsibility of saving their lives fell to Demara, the ship's sole "surgeon." Demara, who allegedly possessed a photographic memory and unusually high IQ, ducked into his quarters with a medical textbook and emerged to save the lives of every single man, including one who required major chest surgery."

Ferdinand talked a little about it while on a game show.
