•"Please do not sit here. This is not a bench - it is an art installation by the artist S. Sosva."
I liked this one too. Funny how the ' councils of this world can be decisive, and act quickly, particularly when they feel challenged by any attempt to highlight their cant.
While I agree that they are amusing I can see the Council's point. If they left them more would be encouraged, and these might not be so funny, but more offensive. The Council is then left with the problem of judging which is which, and they end up as censors. And we know where that leads. So the only realistic option is to disallow the lot. The council have been put in a lose-lose situation.
