Satan's Doctor

HELL was extra gloomy that day. For several weeks, Satan was bedridden. As days passed, his condition deteriorated. Nothing helped to improve Satan’s poor health.
"I can’t understand it" declared one of the attendants in exasperation. "We have so many doctors here yet no one seems to be able to do anything helpful."In great pain, Satan said, "What do you expect? That is precisely why these doctors are in hell. They did nothing on earth but make people suffer. Worst of all, they overcharged their patients.""So what can we do?" the attendant asked in a solicitous tone.

After a week, the devil had identified a dozen with no more than ten spirits of the dead. Still he persisted for he aimed to locate a doctor with just a few spirits roaming by the door.Finally, there was a doctor’shouse with just two spirits hovering by the entrance. "That’s the doctor for Satan!" the devil exclaimed.Immediately, he talked to the youngest doctor. "Would you be willing to treat Satan in hell?"The doctor seemed not to mind and was game to go to hell. "No problem. I am bound by my Hippocratic Oath to minister to anyone and anywhere."
"Good," responded the devil attendant with keen pleasure. "By the way, when did you graduate from medical school?" Simply, the doctor answered, "Only yesterday
