What Are The Odds?

Seriously!? The other day, Bridge and I are kicking back, enjoying a nice afternoon/evening over at a friends house, having a bottle of water (each). All of sudden, and I do mean suddenly, I look at my bottle and notice that the packaging date was my birthday! Cool! Then, for grins and giggles, I look over at my wife's bottle. HOLY DEJA VU! The date on her bottle was her birthday, too! WHAT ARE THE ODDS?!!! Don't believe me? The proof is in the pudding - or photo:
