work experiment

A minister decided that a visual demonstration would add emphasis to his Sunday sermon. 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 sermon, the Minister 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 Minister asked the congregation - What can you learn from this demonstration?

A little old woman in the back quickly raised her hand and said, "As long as you drink, smoke and eat chocolate, you won't have worms!"
