Isn't it a pain that the big adverts on the tube are completely inaccessible so you can't defile them even if you find them completely offensive? They probably pay much more to have them there, because not only are the spaces huge but you get a captive audience with no other option but to look. Why can't we have some other form of art up there which actually enriches the lives of Londoners?
I've started to appreciate the kooky tiling now instead...
