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.

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