This holiday has its own backstory. It was created by Hungarian peasants, who, apparently, have a very specific sense of humor. In fact, there are other names for this day, such as Harvest Day. When the crop ripened, there were always many rodents and pests eager to feast on it. It is known that hedgehogs are enemies of mice and rats. Alcohol makes hedgehogs even more courageous, and to be precise, more aggressive. This is what allows them to actively attack rodents, destroying them in large volumes.
