Worms

Four worms were placed into four separate jars.

The first worm was put in a jar of alcohol.
The second worm was put in a jar of cigarette smoke.

The third worm was put in a jar of sperm.

The fourth worm was put in a jar of soil.

After one day, these were the results:

First worm in alcohol - dead.

Second worm in the Cigarette smoke - dead.

Third worm in sperm - dead.

Fourth worm in soil - ALIVE.

So the Science teacher asked the class...

"What can we learn from this experiment?"

Little Johnny quickly raised his hand and said..

"As long as you drink, smoke and have sex, you won't have worms... "
