The anarchist in me always laughs out loud (literally) when I see spoof signs on public transport. There's been something of a tradition amongst revolutionaries (surely 'disillusioned passengers'? M'colleague.) travelling on public transport in London that whenever possible these spoof signs should replace the plethora of existing ones.
So good are the spoofs that we're sure many thousands pass them by each day without spotting them at all. Various blogs out there carry photos of these signs, though we suspect they've been taken by the offenders themselves, shortly after they've been stuck to the carriage wall in, say, a Tube train.
Mix the message is a company that specialises in such literature and offers a massive range of signs for every occasions. It's worth a look for a giggle. We've been featuring a number of our favourites throughout this post.
