Picture Book: Yertle the Turtle by Dr. Seuss

This story is included with three others in a Dr. Seuss Book.  This is the story of a turtle who decides he is ruler of all he sees.  The higher he gets the farther he sees, and so uses other turtles as stepping stones, and caring about the inconvenience he is causing for others; until one of the turtles at the bottom burps.  Sometimes if you use others, all you have influence over is the mud.  Dr. Seuss has great insight in this story, and it is well told, drawn and rhymed.
