Happy 4th of July!
Might I recommend you conduct a dramatic reading of the Declaration of Independence tonight? It's become our tradition. And a good tradition it is. And the more drunk you are, the more you'll capture the true spirit of our Founding Father (man, those boys could drink!).
It's good to remember what a monumental and daring concept it was to declare independence from The Mighty British Empire. And it's always good to remember and continue to strive toward the more noble ideals our country was founded on.
If you're short on time or attention span, the first two paragraphs and the last one are the meat of the declaration. But really, just read it all. It's not too long. And people really did risk their lives, fortunes, and sacred honor so you could fire up the grill and watch baseball (And yes, it's OK to smirk when you come to the part about "merciless Indian savages"!)
