Just wondering ....

1. If "1 book" is singular and "2 books" is plural, why is "0 books" plural?
2. What am I supposed to do with all those buttons that come with new clothes? I've never lost a button on a garment yet.
3. Can you really expect the unexpected?
4. Poker? On the sports channel? Really?
5. Bottled water. 'Nuf said.
