Save Dracula's Library

This gentleman came in and Teri and I were wondering why we need to save Dracula's Library? We were all for it. Both of us thought, "Sure! Sign me up". But then he turned and I read his shirt properly. It says, "Save Dacula's Library"... which makes so much more sense. Then we got all upset! What's wrong with Dacula's Library!? What can we do? He reassured us that the Library had been saved. It was an old Tshirt.
