Holy cow, I wrote a book!
I then had to laugh because in Swedish, "Stor-Mor" means "Big Momma".
It's not restricted to Swedish. On my trip to Germany last year, my travelling companions found several German signs amusing:
When he told some German colleagues about this hilarious town name, they just looked at him as if to say, "What about Bad Kissingen? It's a nice town. What's so funny about it?" Only when he suggested that they look at it in English did they see the joke.
For some reason I love multilingual jokes.
