Time Travelling on the Tube

I love the precision of the wrongness of this sign that Luke Bozier took on the London Underground


Luke said that this wouldn't happen anywhere but London. I think it's something that wouldn't happen anywhere but the Tube. They seem to have a thing on joking about the time. Remember the energy saving April Fool at Wood Green station with the clocks being decommissioned to save power. I wonder what the point of having clocks on the Tube is?
