Reposting because I don't know how to edit or delete the earlier message, which someone who knows how can. The first line of the poem is the same as the title of the book, "William and Mary." All that is repeated in the book is "William and Mary" and "Then Will--." Does anyone know if there is any more to it?

Okay, this one is killing me. In the young adult novel "William and Mary," by Penelope Farmer, William, who is visiting Mary's family, starts to recite a poem at the dinner table which Mary knows ends with a very rude line indeed. Mary waits, wondering if William will really say *that* in front of her parents. He gets as far as, "Then Will--," pretends to forget how it ends, and asks Mary if she remembers, causing her to lose composure.

Does anyone know if this is a real limerick, or made up for the story? Thanks.
