Fantastic Fables by Ambrose Bierce: Physicians Two
A WICKED Old Man finding himself ill sent for a Physician, who prescribed for him and went away. Then the Wicked Old Man sent for another Physician, saying nothing of the first, and an entirely different treatment was ordered. This continued for some weeks, the physicians visiting him on alternate days and treating him for two different disorders, with constantly enlarging doses of medicine and more and more rigorous nursing. But one day they accidently met at his bedside while he slept, and the truth coming out a violent quarrel ensued.
"My good friends," said the patient, awakened by the noise of the dispute, and apprehending the cause of it, "pray be more reasonable. If I could for weeks endure you both, can you not for a little while endure each other? I have been well for ten days, but have remained in bed in the hope of gaining by repose the strength that would justify me in taking your medicines. So far I have touched none of it."
