Drinking Lesson

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. Observe the worms closely," said the professor putting a worm first into the water.

The worm in the water writhed about, happy as a worm in water could be.

The second worm, he put into the whiskey. It writhed painfully, and it quickly sank to the bottom, dead as a doornail.

"Now, what lesson can we derive from this experiment?" the professor asked.

Little Johnny raised his hand and wisely responded:

"Drink whiskey and you won't get worms!"
