Today is National Punctuation Day -- see http://marquee.blogs.cnn.com/2008/09/24/happy-national-punctuation-day/!
Within that post is a link to an article that will cause heart palpitations in any lawyers you know who deal with contracts: an extra comma in a contract resulted in an increased charge of 2.13 million (Canadian) dollars to one of the parties. I hope whoever typed/word-processed that contract for the party getting the extra money got a bonus of some sort.
If you're looking for an appropriate way to celebrate, try making this resolution: I will not automatically put an apostrophe before the final 's' in a word, unless it indicates a contraction, or a possessive. (Yes, such a resolution is legal.)
