Shhhhhh! Don't give away the secret. When a man is married with children, the john is usually the only place he can read undisturbed. At one time I would go through the entire Sunday newspaper there, back when I read newspapers.
When my Star-Trek-fan kids were growing up, and I'd take something to read into the bathroom and turn on the light, the kids would announce that "there's a radiation leak under the bathroom door."
