A man taking on a late night walk when he hears a strange sound coming from an old mental hospital down the road.

As he approaches he realizes he's hearing chanting. He approaches the building and hears "sixty-seven! Sixty-seven! Sixty-seven!" He gets closer to investigate but the fence is too high to see over, though he does spot a small hole in the wood. He leans over to peep in and as soon as he does a finger pokes him in the eye, and he hears the man on the other end shout "sixty-eight!"
