When I was not very tall, I was told that when you flick up the lid of a lighter, the flint gets struck and the flame ignites. So I thought it only sensible that when you push the lid back down, the flint would be struck from the other direction, thus the flame would go out.
Actually, I wouldn't be surprised if that's what really happens.
