Tuffi was a 3-year-old circus elephant. In 1950, her owner decided that it would be great publicity for Tuffi to take a trip on the monorail. Tuffi, on the other hand, wasn't too keen, broke through the window and jumped out of the car, falling five metres into the river below.
(Tuffi was fine, by the way.)
