It was the last class of the school. The substitute teacher walked in.
She asked, "Okay children, what to do in this class? Should I teach or play a video?"
All the students shouted, "Yes!!"
She sat on the computer and started the projector. On the internet, she played: 'The evolution of Earth and Heroes.'
When the Earth was in its early stages, she got hit by another planet which led to the formation of three satellites: Pubon, Buton and Metron.
