"The crayfish are alive when they die."
Translation:Kräftorna är levande när de dör.
Haha, this is a literary allusion. Johan Henric Kellgren (1751–1795) wrote the funniest poem of his time, Dumboms Lefverne ('The life of Dunce') (1791)
The Dunce in the poem has many ideas, for instance in literature he prefers a clear style, because, as he puts it, the simpler, the easier. ('Ju simplare, ju enklare'). He is also impressed with how Providence has placed rivers everywhere where there are big cities…
He is very moved when he sees crayfish crawling in the pan, about to get cooked, (as you probably know, crayfish should be alive until cooked) because (original spelling):
»Nej, ingen dör så grymt som dessa,
— Skrek han — ty de dö lefvande.»
»No, nobody dies as cruelly as these,
– He cried – for they die living.»
Before I read the comment of Ilmolleggi, I also thought that this what we call lapalissiano in Italian. This name comes from Jaque de la Palisse a French military officers that, if memory serves my right, died in the battle of Pavia in 15 hundredth. Lapalissade is imported from French and used in English very rarely I think.
That word was so confusing for me. I bought a magazine in French at the airport in Nice in 2006 or 2007, to read on the flight back home, and lapalissade was used twice in one article. My French wasn't very good at all, and I really couldn't figure out what it meant. Today, I'd have just looked it up on my phone, but back then, I had to wait until I got back home to check. :)
