I don't think I could think of a better one than that, but I have a little story...
Many yonks ago (way before mobile phones existed), I took charge of a new car. A British-made car. Car worked fine for a couple of weeks, except I'd heard a tinny bang, but since the car seemed OK, I ignored the noise. One day we were travelling through countryside, at least 10 miles from any petrol station. Petrol guage showed more than a quarter full. Car stopped in the country lane and wouldn't re-start. For some reason, I deduced that the guage was not showing the right picture, and decided that I had to go the 10 miles or so to get petrol. But how? There was no traffic in the lane.
I had noticed a parked car further back in the lane, and went to find it. Well, it was still there, but you might guess what was going on inside. After tapping the window and I waiting a polite 5 minutes, the disconsolate couple peered out of the window to find out what I wanted! When I told them the situation, there was a look of despair on their faces, but they agreed to take me to a petrol station, and so that is how my problem was resolved!
The cost to me? A new pack of Durex to provide for their future adventures!
Oh, and what had happened to my car? The fuel tank had imploded!
