A chemistry professor wanted to teach his class a lesson about the evils of alcohol, so he prepared an experiment involving a glass of water, a glass of whiskey, and two worms.

"Now, class," he began with a serious tone, "observe carefully."

He placed one worm into the glass of water. The worm swam around happily, clearly unaffected.

Next, he dropped the second worm into the glass of whiskey. The worm immediately shriveled up and died.

The class sat in stunned silence.

The professor looked at them and said, "And what does this experiment prove?"

A student, eager to contribute, raised his hand and said, "It proves that alcohol is harmful and will kill you!"

The professor smiled and said, "Not quite."

He walked over to the worm in the glass of water and said, "The lesson here is: If you drink whiskey, you won’t have worms!"
