One of the cleverer
graffiti I've seen has become a
meme and spread so widely that it's now found in
trains all over
Sydney. Each one of these trains displays, in every
carriage, a
warning poster which says:
At night, travel near the guard's compartment marked with a blue light.
Some
smartass sometime realised that, by scratching away parts of the poster or through careful use of
liquid paper, this message can be modified to read:
At night, rave near the guard's compartment naked with a blue light.
...and several dozen
wannabe smartasses have since stolen the idea and vandalised many copies of the poster with voracious abandon.
Of course, if the authorities had written the message unambiguously in the first place (is it telling me to travel marked with a blue light?) then the whole thing would never have got off the ground. I'm glad it did.
