A man leaves his house every morning to walk to work and passes a mental hospital surrounded by a wooden fence. Every morning the patienta are out in the yard and he can hear them saying in unison,
" 10, 10, 10, 10, 10".
One day, he gets curious and looks trough a hole in the fence.
Suddenly , a stick shoots out and pokes him in the eye.
" FUCK!" he says to himself.
While walking away pissed off he can hear the patients saying,
" 11, 11, 11, 11, 11".
