There were 5 pencils
One of the Pencils did not have an eraser
The other pencils always made fun of him for not having an eraser
One day, he snapped!
I broke a pencil for you, I hope Your'e happy
After him getting so upset, he realized that he should stay true to himself.
So then whenever the other pencils made fun of him, he said "To thine own self be true."
This logic made all the other pencils snap in awe.
