Why would it be funny though? Am I missing something?

Since you mentioned Mosaic, this came to mind. There are also a handful of OReilly books. I think it'd be funny because you gave us basically nothing to work with, so for her to pluck the exact right one from the thousands of possibilities would be impressive, lol.
