Tseitelman rushed to the rabbi to ask him what to do about an appendicitis attack. The rabbi prescribed a regular dose of cabbage. Miracle of miracles, within three days, Tseitelman returned to the rabbi to advise him that he had been cured. The rabbi, extremely satisfied, wrote in his notebook, “If a man comes to you with a case of appendicitis, cabbage helps.”
The next week Shapiro came to the rabbi with a case of appendicitis. The rabbi checked his notebook and promptly prescribed a diet of cabbage. Within a day, Shapiro was dead.
The rabbi again pulled out his notebook. Where it was written, “If a man comes to you with a case of appendicitis, cabbage helps,” the rabbi added, “in fifty percent of the cases.”
