When hell freezes over or something like that
A pig was flying. And everyone who said that they would do something when pigs flew had to do it. Confirmed bachelors got married. High school drop-outs re-enrolled. Gym memberships soared. People were busy sorting out old promises that no one paid much attention to the airborne pig. Who was only carrying out a vow he had made to his father as he was being dragged away by the butcher. He had sworn that he would fly before papa pig became Sunday roast. And it was Saturday already.
