Doreen has a tooth taken out, and that night she dreams that her various body parts (mouth, brain, tummy, glands, chest, heart, hands, legs and neck) are having a conversation. Each part claims that it is the most important, but eventually they realise that they each have a unique and equally important job and by working together for the greater good they can achieve their goal of keeping Doreen healthy. The brain then concludes by claiming that humans should follow this good example of team work and 'the world will be all the better for it'.
