From Springfield to Land's End
It is a show known for its unusual take on life, but even the most ardent Simpsons fan could not have predicted the contents of this year's Christmas special.
There will be no digs at US foreign policy or bloated celebrity egos. Instead, the show's producers have decided to use their yuletide slot to voice support for a cause that probably does not weigh heavily on the mind of the average American - Cornish independence.
As part of a special UK programme to be shown on Channel 4, Marge and Homer's socially committed daughter Lisa will tear round the house, shouting: "Rydhsys rag Kernow lemmyn." This translates as "freedom for Cornwall now".
Matthew Clarke, of the Cornish Language Fellowship, said he was approached last week by the the team behind the Simpsons. "They wanted Lisa to take up the call for Cornish independence," he said.
Yeardley Smith, who provides the voice for the earnest eight-year-old, has already recorded the segment, and the show is set to go out as an alternative to the Queen's speech, said Mr Clarke.
"It gets the notion that Cornwall is something special, something different, out to a wider audience," he said.
Asked whether he feared the show risked ridiculing the language and the few people who still speak it, Mr Clarke said:
"I don't think The Simpsons can do much harm really. People always look at it in a light-hearted way. I don't get the impression they are looking to directly poke fun."
According to the Fellowship's website, Cornish is thought to be spoken fluently by just 300 or 400 people, although up to 10,000 are said to understand some basic sentences or the odd phrase.
