Confusing Tourists on the Tube

Am I alone in finding this very funny?

Yes, I know it's wrong. Yes I know how important tourism is to the UK economy (well there's bugger all else!) but all the same: the people that go to the effort of printing off stickers that are good enough to fool, aren't just your average graffiti hoon - come on, they spent time planning this - that is why it is sooo funny!

(If nothing else just imagine the Germanic confusion at such a break down of rules!)
