Stephen Fry: Can we settle an important question? How do you pronounce your last name?
JK Rowling: It is Row-ling. As in rolling pin. (mimics rolling action)
Stephen Fry: So if any of you hear someone pronounce her name "Rohw-ling", you have my permission to hit them over the head with -- not with Order of the Phoenix, that would be cruel. Something smaller, like a fridge.
