Cornwall County Council is more than happy to pick up wet leaves from the streets of Newquay, but will not clear dry ones because it says they are the responsibility of the borough council. It all appears to be down to what a fallen leaf really is and when a fallen leaf becomes a dangerous leaf.

Richard Mauger, area surveyor for the county council, said dry leaves were "litter", [the borough council's] responsibility. But if the leaves became wet and could present a hazard, the county council's sweepers would act.

I'm surprised to hear that the phrase "Va va voom" - which entered the Oxford English Dictionary last year - was "introduced into the English language" by Thierry Henry. I distinctly remember first hearing it from the lips of Yogi Bear some time between 1961 and 1964.
