Tomfoolery
It's April Fool's Day an Tomfoolery , one of my favourite books in my childhood came to mind. It collated all sorts of nonce and nonsense, including this old chestnut of a rhyme: One fine day in the middle of the night Two dead men got up to fight Back to back they faced each other Drew their swords and shot each other. ( Full poem here - also includes a discussion of variants and related folk poems) To this day I can still quote that first verse by heart.
