Why shouldn't electric plugs screw in?

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
If your appliance or electronic catches fire the first thing you should do is unplug it if you can. You can't do that with a screw plug.
