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,
responded
confidently, "Drink whiskey and you won't get worms."
