London Underground wants your lines.

TFL is working on its next round of lovely poetic posters to encourage us all to behave like evolved human beings. You know, the ones that politely suggest we please refrain from scoffing stinky kebabs on the tube, and to for gods sake turn those down wretched headphones…but in a slightly nicer, more charming way.

But this time they’ve opened them up for the public to write.

Of course, we are up to our ears in TV ads which have an amateur poem for a voiceover. But we think you can never have enough poetry in a poster.

So, to all creatives with a repressed Gordon Comstock inside of them – give it your best shot.

The winning poem will not only end up on posters right across the network, but the winning lines will feature in the cartoons too.

Via Poet of Adland, Rishi Dastidar, whose own effort bears repeating here:

“On the escalator, don’t stop on the left

As those walking down will be bereft.

You won’t have to do anything grand:

Just move to the right if you’d like to stand.”
