I remember my teaching experience many years ago at a local primary school. The children were talking about how the human body works. One 9-year-old girl seemed to have it sorted:

"The body consists of three parts - the branium, the borax and the abominable cavity. The branium contains the brain, the borax contains the heart and lungs, and the abominable cavity contains the bowels, of which there are five; A, E, I, O and U"

Sweet. Wonder if she's a GP now?
