This is a cute one.

Pastor Sauer 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 Pastor reported the following results:
The first worm in alcohol - .
The second worm in cigarette smoke -
Third worm in chocolate syrup -
Fourth worm in good clean soil - Alive.
So Pastor asked the congregation -
What can 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 --
