Counting…..

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 idiot poked me in the eye with a stick.

Then they all started shouting. ’14..14…14…14….’.
