I worked at Foster Wheeler head office in Reading, England many years ago. In the lobby they had this huge oil painting of a North Sea oil rig, with the title of "An artists impression of the 150 year wave" (oil rigs etc are designed to withstand a certain theoretical wind speed - this case one that could eventuate once in 150 years

)
There was a note underneath the painting saying that this size wave had twice been exceeded in the first year of operation


I guess it was back to the drawing board!!
