natural habitat is in the nostrils of nuns over the age of seventy. They are accompanied by Allergephobia, which induces all sufferers to have a deep aversion to anything bearing a remote resemblance to pollen, dust, cats and husbands consuming more than one whiskey and soda.

pickled onions prior to a possible meeting.
