The Worms Experiment

When a professor of chemistry wanted to teach his class a lesson about the evils of liquor, he produced an experiment that involved a glass of water, a glass of whiskey, and two worms. While putting a worm into the glass of water he said. "Now, class, closely observe the worms." The worm in the glass of water writhed about, happy as a worm in water could be. He then put the second worm into the glass of whiskey. It curled up and writhed about painfully, then quickly sank to the bottom, dead as a doornail.

Then the professor asked, "Now, what lesson can we learn from this experiment?" From the back of the class, Thomas raised his hand and wisely, responded confidently, "Drink whiskey and you won't get worms."
