Learned to mind own business?

A joke of the day!

I received this one through my facebook.
It's too funny to keep it myself. So I want to share with my friends.

How I learned to mind my own business:

I was walking past the mental hospital the other day,
and all the patients were shouting. "13... 13... 13."

The fence was too high to see over, but
I saw a little gap in the planks, so I 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."
