A professor of chemistry wanted to teach his fifth 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
As he put the first worm 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,
Who naturally sits in back,
Raised his hand and wisely,
Responded, "drink whiskey
And you won't get worms!"
