The wedding tradition of tying cans to the bumper of the wedding car comes from the French custom of throwing a “charivari” for the couple. The “charivari” was essentially a celebration that took place on a night before the wedding. Neighbors would walk down the streets and bang their pots and pans to make as much noise as possible throughout the village in order to scare away evil spirits. Since cans make noise when dragged behind a moving car, the classic “charivari” was adapted to simply tying cans to the wedding car bumper.
I attached cans to a ‘getaway’ car of a Japanese couple about to depart on their honeymoon. Soaped up the windows, too.
They were not amused.
