My late father (WWII Navy) had a saying: The only thing dumber than a dumb Swede is a smart Norwegian.
Hey! Take that back. I've got family in Norway. You have that joke the wrong way around.
Didn't you know that Norway is building the world's largest zoo? They're putting a fence around Sweden.
And the Norwegian is walking down the road and meets a Swede with a pig on a leash, and he asks "Where on earth did you get that thing?" The pig answers: "I won him in a raffle."
And as the Oslo-to-Stockholm flight is about to land, the pilot announces, "Ladies & Gentlemen, we are about to land in Stockholm, Sweden. Please set your watches back 100 years".
So there!
