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:
First worm - dead
Second worm - dead.
Third worm - dead.
Fourth worm - alive.

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