“Every pencil is filled with a book.” It sounded very poetic to him so he went on to research this: “And as things turn out, a regular no. 2 pencil has enough lead to write about 45 000 words — a small novel.” He does further math calculating how many words are in the Harry Potter series and that writing them (if one were to write with pencils) would take a bit more than “the use of twenty-four pencils.”
