Once upon a time

With due apologies and thanks to my dear and crazy friend UCH:

Once upon a time

Once, because twice would be a repetitive story

A king

One, because two would mean war

Who was married to a queen

One, because two would be drama

They had a princess daughter

One, because two would be a mess

Who was in love with a knight

One, because two would be a soap opera

He received the task of killing a dragon

One, because two would be a titanic feat

The hero had an idea

One, because two would be asking too much

Using a unique magic sword

One, because were they two, it would no longer be unique

With which, he took the dragon's life

One, because it was a dragon, not a cat

Then they proceeded with the wedding

One, because two would mean bigamy

And they lived happily forever

One, because two forevers would be like two infinites

The end

One, because two ends would be complicated

The bad translation is completely my fault.
