A victim of chronic bronchitis called on a well-known physician to be examined. The doctor, after careful questioning, assured the patient that the ailment would respond readily to treatment.
"You're so sure," the sufferer inquired, "I suppose you must have had a great deal of experience with this disease."
The physician smiled wisely, and answered in a most confidential manner:
"Why, my dear sir, I've had bronchitis myself for more than fifteen years."
