I am a little preoccupied, but this ties in with both. Here is what I think is, possibly, the best speech I have heard given. Especially under the circumstance. Remember that Robert F. Kennedy wasn't supposed to speak on the subject and had to break the news of the assassination to the audience. That, and he says the line "My favorite poet, Aeschylus..." That is when you know you are a rhetorical bad-ass.
