Dean and Sam in “Unfinished Business”

Dean

You know I thought, man there's a lot of them Styne's, you know it's like alpha male central. And then I thought, and this is key, I thought, this is bad, but it would really blow if these guys had the book. At least they don't have the damn book.

Sam

Yeah.

Dean

At least the damn book burned, right Sam? But then Eldon Frankenstein hits me with this little fun fact, he says that the book can't be destroyed, says that it can't be slicked, diced, shredded, burnt, drowned, can not be destroyed. Ain't that crazy? Because I know I saw something burn [Sam's phone rings] Sam you answer that so help me.
