Learning to mind my own business
 

One day I am walking past the mental hospital and all the patients were shouting "13 ... 13 ... 13."

The fence was too high to see over, but there was a small gap between two of the planks so I looked to through to see what was happening.

Some doufus on the other side poked me in the eye and the patients started shouting, "14 ... 14 ... 14."
