On the first day of Biology Class the professor arranged a demonstration for the class. He took two earthworms and dropped one into a beaker of water where it wriggled about. He dropped the second worm into a beaker of Ethyl alcohol where it immediately shriveled up and died. He asked the class if anyone knew what this demonstration was intended to show them.

A boy in the second row immediately raised his hand and said, "You're showing us that if you drink alcohol, you won't have worms."
