From a bio of Edward Heath, PM of Britain in the 70s. Heath negotiated Britain's entry into the EU, or whatever it was called at the time. There was a disappointment on the part of other Europeans with the way the Brits dealt with some of the important nitty-gritty of finance.
Pompidou [of France] told Brandt [of West Germany] that Britain was eager to express opinions on the larger geophysical decisions about Europe's future but left the detailed issues of economic integration to France and Germany. 'It is like a husband who leaves all the questions regarding the apartment, the children's education and the holiday plans to his wife--and only wants to concern himself with whether to open diplomatic relations with China.'

I heard it as a husband bragging in a bar, and the punchline being "nuclear war," but still.
