Cars: What makes them go? Part-5

Sweetheart passes me some thick pieces of cable, so we can be towed. As I walk over to a nearby car to ask for assistance, I hear her tell me that they are "jump leads." I've heard of these.

Well, fortunately, at this point, I learn that she isn't entirely sure which nasty bit is the positive, which is negative. I feel on level terms again, though awkward. The couple in the car I had been approaching are watching. I can do one of two things here. I can endanger myself considerably, or simper inanely, allowing the man in the other car to impress his girlfriend no end with his knowledge of electrical currents.
