There's a book?

Lunching with a friend in a fast-food restaurant, I was telling her about a teenager who had rear-ended my car. The teen blamed me for the accident.

"She even called me every dirty name in the book!" I said.

Just then I looked over to the next table where two nine-year-old boys had apparently been paying close attention to my story.

One said to the other, "There's a book?"
