Joe's chemistry teacher wanted to teach his ninth grade class a lesson on the evils of liquor so he produced a glass of water, a glass of whiskey, and two worms. "Observe" he told his class as he began to put one of the worms in the glass of water. This worm swam about freely and looked as happy as can be. He then put the second worm in the glass of whiskey and it to swam about for a moment but then started to shake and fell to the bottom dead. "Now" he asked "What lesson can we learn from this experiment?" "That's easy," replied Joe. "Drink whiskey and you won't get worms!"
