Once upon a time there was a man that found everything funny.
And every day he would continuously laugh at anything that would happen.
Until one day the city had had enough and the mayor sent him away.
And because of this he walked day and night still laughing.
And because of this he passed through many towns and brought his laughter to many people.
Until finally a scientist realized he was from another planet and laughter was his form of communication.
And ever since that day they’ve been running tests and experiments trying to decipher his language.
