"the hunchback in the bell tower,"
A group of tourists visiting Notre Dame in Paris were being taken around the bell tower by a guide when a hunch-backed man ran in, walked over to the giant bell and head-butted it
Despite its massive size, the bell swung up on its pivot then back down again, hitting the hunchback full in the face, and sending him staggering across the tower, over the parapet and down into the street below.
"Who on earth was that?" asked one of the tourists
"I don't know", replied the guide, "but his face rings a bell"
