In a school science class 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. 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, smoke and have sex, you won't have worms."
ha ha ha, very funny. I am reminded of the joke about the eight legged creature. One scientist was investigating the creature'. He trained the creature so that when he says Jump it will jump. First, he tied two legs and said Jump the creature jumped. Then he tied two more legs and said Jump the creature jumped with some difficulty. He further tied two more legs and said Jump and the creature managed to jump. Finally he tied all legs and said Jump repeatedly the creature did not jump. He wrote in his observation book,'If you tie all the legs of an eight legged creature it becomes deaf '. :-D
