Yeah, just as with aspirin, I carry a few of those (i.e.,"souls") in my pocket for emergencies, e.g., in case I need to fend off Satan (an archaic term for an individual evil entity of great power) - I toss a fee on the sidewalk and skedaddle away while He (i.e., the Devil [caps for classicly-attributed respect of his overweening spiritual powers]) devours them.
