Nice and short, as the others said, here's an old one that I wrote for fun, not that I don't have inspiration on the frey, but well...just got up so not much logic in my head right now XD
Happiness in one single move,
So unpredictable and yet so loved.
Beneath that face can hide great plots,
Plots of conquest and plots of destruction.
Many are subdued by its angelic appearance,
They finish as slaves of despair to smiling gods.
The only way to escape this expression,
Is to frown back and take out your tongue.
Full of oozing saliva dripping down off the ground,
Will surely dispel the curse upon you.
For now you know the forbidden secret,
A smile is your doom but saliva is your saviour.
