There’s a marvelous scene in Alfred Hitchcock’s “North by Northwest” where an advertising executive, played by Cary Grant, swipes a taxi from another man by claiming that his secretary is ill. When she chides him for the lie, Grant unblinkingly replies: “In the world of advertising, there’s no such thing as a lie. There’s only expedient exaggeration.”

Her famous claim that the US could save $21 trillion by keeping tighter controls on Pentagon budgets was obviously ludicrous.
