One day Firm A were caught unawares because firm B
had brought out a new disinfectant bottle with a twisted neck
This allowed the housewife to squirt the disinfectant easily under the lip of the bowl
.
Because of the shape of the neck it was called the Duck.
Firm B dramatically improved their share of the market at the expense of firm A
Firm A assembled all their mathematicians one Friday and said that they would have food sent in
but no-one could go home till they had designed an equivalent duck.
This is quite a complicated geometical and fluid flow problem.
The mathematicans completed the jopb.
Firm A marketed their Duck and the market shares returned to what they were before
