Sister Mary Francis wanted to teach her 5th grade class a lesson about the evils of liquor, so she produced an experiment that involved a glass of water, a glass of whiskey and two worms. "Now, class, observe closely the worms," said the nun putting one worm first into the water and the other worm into the glass of whisky. The worm in the water writhed about, happy as a worm in water could be. But the second worm, the one put into the whiskey, writhed painfully. The poor creature quickly sank to the bottom, dead as a doornail. Sister Mary Francis then asked: "Now, what lesson can we derive from this experiment?" Johnny, remembering what his dearly departed father had told him, waved his arm excitedly. "Yes, Johnny?" said Sister Mary Francis. The boy wisely responded: "Drink whiskey and you won't get worms."
