This glorious fable of contractual interpretation comes to us from the Northland (and to me from the SomethingAwful forums). It's always sad when companies accidentally lose jillions of dollars, but I can't say that I'm terribly distressed to see a comma-happy contract drafter get its comeuppance. Commas aren't toys, kids. You don't just stick them into sentences, when it seems like a good idea. Otherwise you look ignorant and, marginally illiterate. Commas have a narrow and well-defined purpose and should not be used, beyond that purpose.
And while we're on the subject of important little bits of punctuation, I suggest you look at this.
