As told via IRC...
Once upon a time in a little hamlet outside Dussledorf, there lived a small
mouse named Harold. Harold liked cheese, so every day he would pinch the cheese
from the mousetrap which the inkeeper always set in the pantry. He didn't take
any of the food from the rest of the pantry, because he was an honest mouse and
didn't steal food.
One day, Harold went to the pantry, and the mouse trap was gone.
As Harold was an honest mouse, even though he was hungry, he didn't take any
of the food from the rest of the pantry. Instead, he climbed up on the innkeeper's
table while the innkeeper was having breakfast.
The innkeeper looked down at Harold.
"Oi!" said Harold. "Why did you take away the mousetrap?"
The innkeeper said "The mousetrap was to catch naughty little mice who sneak into
my pantry to steal the food I have for my guests. If you eat the cheese from it,
the trap is no good."
"Well," said Harold "I am not a naughty mouse, and I don't steal food from your pantry."
"But isn't taking cheese from the mousetrap stealing too?" pointed out the innkeeper.
Harold was rather upset that he was stealing, as he thought the cheese in the trap was
a gift from the innkeeper. He went to a field where there were some cows, put a bucket under
one of them and milked it. After he milked the cow, he churned the milk until it became butter.
After the milk became butter, he dragged the bucket back to the inn and presented it to the
innkeeper, who was by then finished having his breakfast.
The innkeeper was extremely grateful. "I'm extremely grateful," he said. "As the refridgerator
has not been invented yet, fresh butter is hard to come by."
So from then on, Harold provided the innkeeper with fresh butter every day, and the innkeeper
supplied Harold with cheese. And so they lived happily ever after, or at least until bartering was
outlawed and the rulers introduced currency.
The End
