Demonstration

A teacher decided to do a visual demonstration in a class. Four worms were placed into four separate jars. The first worm was put into a container of alcohol. The second worm was put into a container of cigarette smoke. The third worm was put into a container of chocolate syrup. The fourth worm was put into a container of good clean soil. At the conclusion of the class, the teacher reported the following results: "The first worm in alcohol - dead. The second worm in cigarette smoke - dead. Third worm in chocolate syrup - dead. Fourth worm in good clean soil - alive." So the teacher asked the class: "What can you learn from this demonstration?" A little Jim in the back quickly raised his hand and said, "As long as you drink, smoke and eat chocolate, you won't have worms."
