"Next to his house was a piece of broken board which had: "TRESPASSERS W" on it. When Christopher Robin asked the Piglet what it meant, he said it was his grandfathers name, and had been in the family for a long time. Christopher Robin said you couldn't be called Trespassers W, and Piglet said yes, you could, because his grandfather was, and it was short for Trespassers Will, which was short for Trespassers William. And his grandfather had had two names in case he lost one. Trespassers after an uncle and William after Trespassers."
