This quotation is driving me bats!

I am currently preparing a presentation on searching the internet and I'm struggling with a way to introduce the presentation. That's right I have never taught a session on Internet searching. I've always done presentations on specific aspects of the Internet but not this, I'm actually pretty excited about the prospect. I'm going to cover the big three search engines (Google, Yahoo, MSN), evaluating web sites and mining the deep web. I have heard a quote during the last ten years which I think perfectly describes searching the Internet. I would like to use this quote in my introduction and I need some help figuring out the quote and who to attribute it too! It goes something like this...

take a book, remove its binding, table of contents and index, throw it up in the air and try to find what you are looking for ... that is searching the internet.

I've been through the excellent quotation database listing from the Internet Public Library but have had no luck. A Google search is far to broad considering the obvious and popular keywords. Can anyone help? Or have any other suggestions for an introduction? You can e-mail me at ccooke[at]umanitoba.ca.
