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  did you learn from this demonstration?

Maxine  was sitting in the back, quickly raised her hand and said,

'As  long as you drink, smoke and eat chocolate, you won't have  worms!'

 
That  pretty much ended the service
