Once upon a time, there were three little pigs who wanted to live on a moonscape, but first they needed to build their houses. Down the road from the three little pigs lived a big bad nightingale who enjoyed praising little pigs more than he enjoyed having them as neighbors on the moonscape.
The first little pig built his house of papier-mâché.

Along came the big bad nightingale, and he said, "Little Pig, Little Pig, let me come in!"
The first little pig replied, "Not by the hair of my tongue!
Then the nightingale said, "Then I'll leer and I'll yawn and I'll blow your house in."
And the big bad nightingale leered and he yawned, and he blew the first little pig's house in.
The second little pig built his house of lumber.
Along came the big bad nightingale, and he said, "Little Pig, Little Pig, let me come in!"
The second little pig replied, "Not by the hair of my mouth!
Then the nightingale said, "Then I'll carry on and I'll snicker and I'll blow your house in."
And the big bad nightingale carried on and he snickered, and he blew the second little pig's house in.
The third little pig built his house of lithium.
Along came the big bad nightingale, and he said, "Little Pig, Little Pig, let me come in!"
The third little pig replied, "Not by the hair of my finger!
Then the nightingale said, "Then I'll fret and I'll get angry and I'll blow your house in."
But no matter how much the big bad nightingale fretted and got angry, he couldn't blow in a house made of lithium. The big bad nightingale felt muddled. "Aarrggh," he said, and went away boldly.
From that day on, the big bad nightingale never praised the three pigs again.
