Duke: Look, Tony, I told you, I'm good for my bets! I'll put the check in the mail today! Voice: I'm afraid that won't do, old boy. I've already sent my man rond to pick it up in cash. Duke: *Sigh*... alright, Tony, but he'll have to take it in pounds. That's all I've got on hand... Voice: Pounds?! My dear fellow, as fond as I am of England, I must insist on dollars! Duke: For God's sake, man, it's your OWN national currency! Voice: Duke, I'm a patriot, not a fool! Duke: So what the hell am I? The damn Marshall plan? Honey: Excuse me, sir, there's a tank out front.
