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 soil.
After one day:
The first worm, in alcohol---dead.
Second worm, in cigarette smoke---dead.
Third worm, in sperm---dead.
Fourth worm, in soil---alive.
As long as you drink, smoke and have sex, you won't get worms!
