There's a story about a famous old clock that sat above the booths of a bank here in Chile. The bank used this clock as a kind of trademark, you could see it on every leaflet, every catalog and almost every paper this bank issued
One day, two guys appeared with blue overalls, helmets, and a stepladder.
Acting absolutely normal they remove this clock for maintenance reasons.... no one ever saw the clock again! there was no maintenance scheduled... it was the perfect crime!!
