Quasimodo wanted to take a vacation, so he advertised for a temporary bell ringer. Nobody applied until the day he was ready to leave, and then a fellow showed up, but he had no arms! "How will you ring the bell?" wondered Quasimodo.
"Just watch," said the applicant. He jumped up and whacked the bell with his forehead, and the bell gave out a nice rich tone. "Fine, go to it," Quasimodo told him, and picked up his bag and left. Down in the street, he looked back to watch the new hire ringing 11 am. Unfortunately he jumped a little too high, and fell from the tower to the street below. A crowd gathered. "Who was that guy?" they wondered.
Quasimodo turned the body over and said, "I don't know his name, but his face rings a bell."
He went back into the cathedral to resume his duties, but soon another man with no arms turned up. He said, "The dead man was my brother, and I want to fulfill his duties." "Fine, and thanks," said Quasimodo, "but be more careful." He went back down to the street, and turned around to watch the replacement ring in noon. Despite the warning, he got too enthusiastic just like his brother, and fell to the street.
Again, the crowd gathered, and asked "Who is this man?"
Quasimodo said, "I don't know his name either, but he's a dead ringer for the other guy!"
