The Greatest Speech Ever

One of my kids came upstairs just after ended with his girlfriend. I said, "Did you see the Greatest Speech Ever?"
"The Greatest Speech ever?"
"Well, The Greatest American Speech Ever, er, maybe second?"
"OK, second, but what about George Washington's farewell speech?"
"Oh, yes, and then there's the Gettysburg Address"
"And didn't Roosevelt have one?"
"Yes, the uh, there's nothing to fear but fear itself."

Can you think of any others?
