Most Americans have only a vague idea of what Boxing Day is. Yes, it started out as the day we trash the boxes the Christmas presents came in, or possibly, something entirely different; I'm not sure.
Sure, I could have read the whole wikipedia article and parroted it back to you. But I don't look at a thing and wonder what it is; I look at a thing and wonder what it should be. And shouldn't Boxing Day be a day for everyone to take a swing at Sean Penn? I mean, in an ideal world, wouldn't that be best?
