One day the secret agent of Sesame Street realized that his A had gone.
The coat had been too small for the A. It wanted to see the world and visit some relatives.
But what dud the A see? The humans enslaved all other letters and locked them into signs and prints!
This is not fair! A decided to free its friends!
Using some unknown trick, A managed to free all letters. Since then there are no letters anymore.
The letters now live on a far away planet and enjoy their freedom.
