Tunger knivur

that meant heavy knife, right?

First comes heavy breathing, staring at the ceiling

"Tunger knivur" looks like Götaland Swedish; "tunger kniv".

Yes, this line is the most famous, at least here in Sweden. Swedes usually cite it as "donkur knivur", e.g. Agneta Sjödin ( http://www.imdb.com/name/nm0803605/ ) in the swedish late 90's tv show "Småstjärnorna" ("Junior Stars") when chatting with a little "star" girl with icelandic parents. (I think she said something like "I know some Icelandic too; 'Donkur knivur' - Heavy knife".) Whenever a swede meets an icelander this line is quoted. A similar things happens when a swede meets a finn: "I know some finnish; 'Ei sa peitää' - Do not cover". The phrase 'Ei sa peitää' is written on swedish heat elements. remember the tight bounds between Sweden and Finland. Also food manufactured and sold in Sweden and Finland usually has a swedish and a finnish name.

myndin var góð en hún er gömul :)

As the Swedish bloke I am, I'm constantly starting conversations with Icelandic people with "Þungur hnífur" (and we've quite a few Icelandic exchange students at my Uni, they actually don't seem to care - hell, they might even be used to it. :p).
As a conversation-starter it's the perfect line, I got an icebreaker and they know what to reply with (can't remember it in Icelandic at the moment, but if my memory serves me correct, it's something like "The knife is supposed to be heavy").
..and another thing I actually just realized, written Icelandic is _really_ easy for us Swedish people to understand (we might not get each word, but we sure get the meaning of the sentence). :p

..och jag snackar mest strunt. ..man ska inte surfa imdb på fyllan :|
