Here are some Icelandic ones, hope they don't loos to much in the translation:
Too late to cover the well when the kid has fallen into it.
you need to show colour (taken from playing bridge,means you got to make an effort)
That's a dog from next county (whole other story)
Stages of drinking; first you're mild, then after you get a bit in one foot you dust up, then you drink some more and get truly half, and then after putting your back into it you are on your shoulders, perhaps even your earlobes. Then probably you "die", and next morning you wake up dusty. Translation is as direct as possible.
I got to tell you a story of a man, a mercenary and legendary swordfighter in Iceland back in the year 1000 AD, give or take a hundred. He was walking from dale to dale and came where men were hearding sheep. This guy was a few pages short of the full book, and upon seeing a shepherd leaning forward on his staff, he immediately pulled his sword and lobbed the shepherds head of. Now others run to him blades pulled and inquire as to whether he was taking his vengeance on this poor shepherd, or what his crime had been. "none was the crime", said the swordfighter "he just stood so well to be chopped".
Another one cut a leg from a rival soldier and said "You don't have to look again, you were right the first time, your leg is off".
There are more still but I have to work better on the translation to be able to bring the punchline.
