Noticed this sign posting over on Boing Boing, and thought it went well with the theme in recent posts here about signs.
This is one of the most bizarre signs I have ever encountered ... IT'S A SIGN ABOUT THE SIGN ITSELF ... The logic behind the existence of this self-referential sign escapes me! What is it for? Why is it there? Did whoever put it up realize that if there were no sign, there would be no need to warn about it? Is this a joke from the developers? Is it a lesson in recursiveness? Is it a philosophical prop?
