Looting the Library

I promised a while back to write a post describing why so many statistics have a central limit theorem. I went to the library to look up the result I had in mind, to refresh my memory as to the details. The book I wanted was checked out. I thought about requesting the book, but it seemed a bit much to request a book just for a blog post. A couple of days later, I found out who had the book checked out: me.
