There are so many signs in our world, aren't there? Signs to tell us where to go, signs to tell us what — and what not — to do, advertisements, warnings, and so many more.
It's no wonder that we've developed a bad habit of glazing passed them without much notice. While that can be dangerous if it's a stop sign, it usually just means that the makers of the sign need to work harder to make us notice.
Some do it with brutal honesty, but some are just funny.
