The second and last selection comes from another cartoon, Mr. Magoo's Christmas Carol. Its title, We're Despicable, comes from the first line, but it's also known as Plunderer's March. In this scene, the three plunderers go to a pawn shop to see how much money they can get for things they've scavenged from the bedroom of a recently deceased "stiff". The pawnbroker joins them in some musical self-deprecating humor.
