I don't know everything about librarians, but I do know that some of them are into tattoos. And by "into tattoos" I mean that they have ink work that would make Henry Rollins pause for admiration.
I can't get a tattoo (long story, it has to to with genetic bleeding problems and original sin) but if I could, I'd probably get something like those pictured in this gallery of literary tattoos. Though I wouldn't get the Vonnegut quote from Slaughterhouse Five. I'd be more inclined to get "Hi Ho" from Slapstick.
I'd like to get a tattoo over my whole body of me, but taller. ~Stephen Wright
