"I'll set him to work in the library," he says, giving Dean a nod. "That place hasn't been cleaned in a decade."

"Careful," says Dean. "You'll come back one day to find it alphabetized and cross-referenced."

Bobby grunts and nods his head, and if he's anything like Dean, letting Sam loose in there'd mean he'd never find anything again. "The kitchen then," he says. "He can alphabetize my soup all he likes."

a) The fact he has a library.
b) Just cross referencing love because Sam is such a geek that he would do it.
c) ALPHABETIZE SOUP. LOL. XD

Glad I stuck around to read this. (Yay. No torture instruments Clowns.)
