A science experiment.

In a science class, 3 worms were placed into 3 separate jars.

The first worm was put into a jar of whisky.

The second worm was put into a jar of cigarette smoke.

The third worm was put into a jar of soil.

After one day, these were the results:

The first worm in whisky ---dead.

The second worm in cigarette smoke --- dead.

The third worm in soil --- alive!!

So the science teacher asked the class --- "What can you learn from this experiment?"

Little Johnny quickly raised his hand and said.

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