The number one book on "number two" will give kids a whole new perspective on the past "Did lead pipes cause the fall of the Roman Empire?""How many toilets were in the average Egyptian pyramid?""How did a knight wearing fifty pounds of armor go to the bathroom?""Was poor hygiene the last straw before the French Revolution?""Did Thomas Crapper really invent the modern toilet?""How do astronauts go in space?" History finally comes out of the water-closet in this exploration of how people's need to relieve themselves shaped human development from ancient times to the present.

A blend of historical photos and humorous illustrations bring the answers to these questions and more to life, plus extra-gross sidebar information adds to the potty humor.
