A Funny Story

A professor of chemistry wanted to teach his 5th grade class a lesson about the evils of liquor, so he produced an experiment that involved a glass of water, a glass of whiskey, and two worms."Now, class, closely observe the worms," said the professor while putting a worm into the water.The worm in the water writhed about, happy as a worm in water could be.He then put the second worm into the whiskey. It curled up and writhed about painfully, then quickly sank to the bottom, dead as a doornail."Now, what lesson can we learn from this experiment?" the professor asked.Johnny, who naturally sits in back, raised his hand and wisely, respondedconfidently, "Drink whiskey and you won't get worms."
