A delivery man went into a mental institution to deliver a package. On passing one of the rooms, he heard 'thirteen, thirteen, thirteen' over and over again. He raised an eyebrow and passed on.
After delivering his package he went back through the same route, and again passed the door...'thirteen, thirteen, thirteen' he heard again...unable to contain his curiosity, he peeked through the keyhole to see what was happening.
Suddenly, a straw came through and poked him in the eye!
He stood up, clutching his face and heard..
'fourteen, fourteen fourteen'
