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 jar of alcohol. The second worm was put into a jar of cigarette smoke. The third worm was put into a jar of sperm. The fourth worm was put into a jar 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 the cigarette smoke – dead. The third worm in the sperm – dead. The fourth worm in good clean soil - alive and well.

So the minister asked the congregation, "What can we learn from this demonstration?"

A little old lady in the back raised her hand and said, "As long as you drink, smoke and have sex, you won't have worms."
