Rusty and Linus in Ocean's Eleven:
Rusty: You look down, they know you're lying... and up, they know you don't know the truth. Don't use seven words when four will do. Don't shift your weight, look always at your mark but don't stare, be specific but not memorable, be funny but don't make him laugh. He's got to like you then forget you the moment you've left his side. And for God's sake, whatever you do, don't, under any circumstances...
Livingston: Come look at this?
