At Least It Rules Out ‘Twilight’

(I work at the reference desk, and I often help patrons find books. The following exchange happens one morning:)

Patron: “Hi, I’m looking to see if you have a book.”

Me: “I can help you, then! Can you give me the name of the book?”

Patron: “I don’t remember it.”

Me: “Well, do you remember the author’s name?”

Patron: “No… but it was about vampires and it had the word ‘blood” in the title.”

Me: “…That doesn’t narrow it down nearly as much as you think it does.”
