A patron asks a librarian for a book called "Oranges and Peaches." The librarian asks, Do you happen to know the book's author? The patron replies, Oh, it's by someone named Darwin. I have to read it for a class. The librarian finds a copy of "The Origin of Species" for the patron.
And speaking of geography...
...this map is cool. Countries are labeled by the two-letter country codes that are used in URL extensions.
