An exhaustive test was done, and here are the results

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, these were the results: The first worm in alcohol - dead. Second worm in cigarette smoke - dead. Third worm in sperm - dead. Fourth worm in soil - alive.                                             Lesson: As long as you drink, smoke and have sex, you won't get worms.
