Tough to choose a favorite. John Wayne, Winston Churchill, The Gipper, and yes Scarlett O'hara also come to mind.
For now, I'll go with "The Duke" on this one.
“I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them.”
I admire simplicity. When he spoke, I don't recall ever having to figure out what John Wayne meant.
