I can't remember the source of this, but by context this inversion of the trope was presented as a true story by a male Jewish comedian old enough to have served in World War II. Drafted into the armed forces, after a few days of basic training the comedian consulted the camp doctor, convinced that he was dying because his "fire had gone out". After some discussion, the doctor explained that the serviceman was so used to having heartburn that he thought that not having it was a medical emergency.
