When Was The Last Time You Used A Phone Book?

Do you still use your phone book?  As a phone book, I mean.  Not as kindling or to keep a piece of furniture level.

If not, when was the last time you used it?

Personally, I can't remember the last time I used one. Google is way more efficient and links to a map showing me where the business is located.  And, if we're talking about people (instead of businesses), I just use Facebook.
