An Extra Brick
This protruding brick sends our imaginations into overdrive. If we push on it, will we get access to a secret chamber of some sort? Is it a passageway into magical candy land?
I’m sorry to break it to you, kids, but this brick will lead you to nowhere land. As in, it will take you absolutely nowhere in particular. You’ll just be the strange person on the street pushing this irritating and unsightly brick over and over hoping for some magic vortex to appear. How this brick was put so out of line with the others without anyone wanting to fix it is a big mystery.
