So….
I was walking past the mental hospital the other day, and all the patients were shouting, "13...13....13...13." The fence was too high to see over, but I saw a little gap in the planks and looked through to see what was going on. Some bastard poked me in the eye with a stick. Then they all started shouting. "14...14...14...14...".
Bet ya saw that one coming.
