Calvin wants to know why girls are so weird

Ask any question to the "Ask a Librarian" and the Chicago Public Library will answer your question. I've done this about five times now, and even if they don't have a resource in their system, they will point you to another way to get your answer. Today I asked them the following question:

Do you have any books on why girls are so weird? My friend Calvin was asking this question today. Here's his full question: http://www.gocomics.com/calvinandhobbes/2012/10/19

This is my goofiest question I've asked them yet. I hope they respond. Oh, btw for the record, I don't think girls are weird. They are wonderful.
