At a certain monastery new monks were required to get up early, go to the bell tower and pull the rope to call the other monks to morning prayers. The newest monk dutifully got up and went to the bell tower, only to find to his chagrin that the bell was missing its clapper. Not knowing what else to do, he got under the big bell and ran back and forth, hitting his head against the inside of the bell. This succeeded in waking up the other monks; the new guy staggered out of the tower and collapsed on the lawn.
Two monks walked by; one said "Hey ,who's the new guy?" The other said, "I don't know his name, but his face rings a bell."
