Worms and Alcohol
A science teacher wanted to teach her 6th grade class a lesson about the evils of alcohol, so she produced an experiment that involved a glass of water, a glass of whiskey and two worms.
"Now, class. Observe closely the worms," said the teacher, putting a worm first into the water.
The worm in the water wiggled about, happy as a worm in water could be. The second worm, she put into the whiskey. It writhed painfully and quickly sank to the bottom, dead as a doornail.
"Now, what lesson can we derive from this experiment?" the teacher asked.
Little Johnny, who naturally sits in back, raised his hand and wisely responded, "Drink whiskey and you won't get worms!"
