A man is strolling past a lunatic asylum when he hears a loud chanting. ‘Thirteen! Thirteen! Thirteen!’ goes the noise from within the mental hospital’s wards.
The man’s curiosity gets the better of him and he searches for a hole in the security fence. It’s not long before he finds a small crack, so he leans forward and peers in. Instantly, someone jabs him in the eye.
As he reels back in agony, the chanting continues:
‘Fourteen! Fourteen! Fourteen!’
