Gone With The Wind Library Display

I came in for my volunteer stint at the library and Librarian Trevor asked what my favorite call number is.  Trevor loves puns and jokes so figured this was a variation on that theme.  Maybe among librarians, your fav call number (I do like the 520's) is similar to a Christian's fav verse (Philippians 4:8)?  Reminded me of an idea I thought Trevor would like.  I'd recently saw a sign:

"Dinosaurs didn't read books.  Dinosaurs are now extinct.  Coincidence?"  Why not have a library themed pun/joke/saying each day?  Maybe add it to the village's digital bill board?  Put on the library's website?  Write it on the white board by the front door of the library?  He seemed to take to the idea.  Might be a fun way to encourage people to check out the library.  Remember, one of the great things about books is there are no pop-up ads.
