One day, a teacher brought two buckets into the classroom.
One bucket was filled with water, and the other was filled with beer.
He then led in a donkey and placed both buckets in front of it.
The donkey sniffed each one, thought for a moment, and chose to drink the water.
The teacher turned to the class and asked,
“So, what lesson can we learn from this?”
Little Johnny quickly raised his hand.
“Yes, Johnny,” the teacher said. “Tell us.”
Johnny smiled and replied,
“I learned that anyone who doesn’t drink alcohol is a donkey.”
