I have been checking this thread periodically to see if someone would pipe up with this gem of a phrase. Amazed it took post #274.
My own thoughts on the original discussion: as much as I think a life-ban from football for running on the pitch is draconian, I also realise that one would have to have lived under a rock for many years to not be aware it is an offence, and sooner or later someone, somewhere was going to fall foul of it. In my view, similar deal to speeding: every one knows that the limit in a built up area is 30, many people go faster and get away with it and don't consider it a problem, but it is an absolute, and one day you'll speed past the copper who decides to take you in for it.
