Five shiny robots

5 Shiny Robots
Five shiny robots, playing marbles on the floor,
One went home and then there were four,
Four shiny robots, playing in a tree,
One went home and then there were three,
Three shiny robots with nothing left to do,
One went home and then there were two,
Two shiny robots, think of something fun,
One went home and there was one,
One shiny robot pretending to be a hero,
His mother called him home and then there were zero.
