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 last worm was put into a jar of soil.
After one day:
First worm died.
Second worm died.
Third worm died.
Fourth worm was still alive.

Lesson:
As long as you drink, smoke and have sex, you won't get worms.
