A method with class.

Bank robbery and swindling are both methods to separate fools from their money, but bank robbery involves violence, potentially death and a long prison sentence if you get caught; swindling involves poise, timing, manners and intelligence and if you get caught they're less inclined to lock you away with a 180 pound gorilla called Bubba. Thus swindling is a class method and bank robbery isn't.
