Seious Side: "I have nothing to offer but blood, toil, tears, and sweat." -- Winston Churchill rallying the British people. You don't evoke courage, bravery, and sacrifice by telling people everything's okay.
Less Serious: Churchill again: "Lady Astor: Winston, if you were my husband, I would put poison in your tea. Churchill: Madame, if you were my wife, I'd drink it."
Jack Nicholson (Five Easy Pieces): "I'll have a chicken salad sandwich. Hold the mayonaise, hold the lettuce, hold the tomato, hold the chicken salad."
And, for the Slightly Older Guys: Dean Wurmer to the Delta Frat (Animal House) "And you'll be happy to know that I have notified your local draft boards that you all, all eligible for military service."
