"Brick" a brack...

Our brick mason, Keith, is repairing the back outer wall of the building, pulled one brick out, and this is what came out with it

Oopsies!

The lesson for today kids: never put tar over your bricks.  It sticks to the bricks like, well, tar, it's impossible to remove and moisture gets trapped behind it and screws up your brickwork. 

This is where the bad bricks came from (no surprise - it looks terrible).
