Today's was this:

"On Sept. 15, 1789, the U.S. Department of Foreign Affairs was renamed the Department of State."

What is really cool about this factoid is a related factoid. Prior to being called the U.S. Department of Foreign Affairs it was called the Committee of Secret Correspondence and was headed by Ben Franklin. The prime duty of this office was to secretly open and read personal mail of those they suspected of had allegiance to foreign nations. Not so different than what the NSA is doing with phone calls today. The Opposition Party thinks this is unconstitutional yet the original program was developed by Ben Franklin. I know they oppose spying, but what is their plan for catching the bad guys?
