This guy is down the street right beside a huge wooden fence which encompasses a large mental health facility. He is headed down the sidewalk and keeps hearing what sounds like a large crowd on the other side chanting, "thirteen, thirteen, thirteen, thirteen, thirteen..."
It gets louded as he's walking until the chanting is nearly deafening. He turns towards the fence and notices a little knothole in the wooden fence. He can't stand the suspense and bends forward to look through the hole.
Instantly he is poked in the eye by a big grubby finger!
He stumbles backwards grasping his eye, which is watering heavily now...and hears...."forteen, forteen, forteen, forteen, forteen........"
