Everything about this story is hilarious.
Firstly, the fact that a town name more or less forces matronly women to say the word "fuck" in everyday language is genius. There's nothing funnier than a ham-like matron opening her eyes widely and saying a naughty word against her will.
Secondly, the (self appointed - well, not necessarily but it's hilarious to think about pushy women who appoint themselves spokespeople for a small village that is offended by something) spokeswoman for the town said the following:
"There should not be any doubt at all that, as a result of relatively new associations, the pronunciation and spelling of the place name 'Fjuckby', today arouses ridicule, teasing and hilarity in the general public," wrote inhabitant Katriina Flensburg on behalf of her fellow villagers.
And thirdly, derivatives of the word "fuck" in English can be traced back to Shakespeare not to mention the fact that the middle section of the word "fjuckby" actually means the same in Swedish as "fuck" does in English.
Oh, you villagers. . .with your dog like nature that adores being kicked...
