Whats wrong with this picture?

First of all, well done to the Gunners last night. Of course I'm disappointed we didn't win, but you need a bit of luck and I think Barcelona had it on their side. We played our hearts out and thats all any fan could ask.

Anyway, on my way home I took this at clapham junction, sorry for the bad quality but it made me laugh, can you see why? :)
