No, it's not some fake holiday sponsored by a colonics trade group. It's the day the Brits finally left New York after we won the Revolutionary War: "As George Washington triumphantly proceeded Downtown, jeering Americans on Staten Island were fired upon by a British ship in what has been described as the last shot fired in the war." Kind of like how your Brit friend always has to buy one more iPhone or Prada bag before they leave because they're sooo cheap here? The Brits were subtly bitchy like that even then. [City Room/NYT]
