The "two full moons in a month" definition is recent and somewhat bogus, like the bit about the seasons officially starting on the solstices and equinoxes. Originally "once in a blue moon" meant "pretty much never", and the modern definition stems from an error made writing a question/answer for Trivial Pursuit.
Yeah. Also, for glasses, I think we should just wear 2009 glasses and take them off in celebration and toss them high in the air to ring in the new year, instead of wearing a "1" on our noses.
