Boo.
Ooo spooky, the Caption Competition is back! Have you missed it? Leave us a caption to this week's Photo of the Day in the comments below and get us all in the mood for Halloween this weekend.
And if nothing witty comes to mind, be sure to remind yourself of the ghoulish events happening this weekend with Londonist's Halloween round up (Part 1 and 2).
