Worms

Four earthworms are placed in four separate test tubes:

1st in beer 2nd in wine 3rd in whiskey 4th in mineral water

The next day, the teacher shows the results:

The 1st worm in beer, dead.

The 2nd in wine, dead.

The 3rd in whiskey, dead.

The 4th in mineral water, alive and healthy.

The teacher asks the class:

• What do we learn from this experience?

And a child responds:

• Whoever drinks beer, wine and whiskey, does not have worms.
