I have some as well.
One day a norwegian man went to see the swedish king.
"The swedes tell all these mean stories about us norwegians. They say that we aren't as smart as them!" he said to the King.
The king said "There, there. I'll show you that us swedes aren't that bright either."
He called out to one of his servants and said: "You there! Go to my house and check if I'm home!"
When the servant had left the king turned back to the norweigan and said:
"See, he wasn't that smart either."
"No, he could have called instead.", the norwegian answered.
How do you sink a norwegian submarine?
A: You swim down and knock on the door.
How do you sink a norwegian submarine again?
A: You swim down and knock on the door.
They'll open it and say:
-Ha! You won't trick us this time!
A swede is travelling in a hot air balloon when suddenly a strong wind makes him drift over to norway. The man doesn't know where he is so when he notices a man on the ground he asks:
-Where am I?
-Don't try to trick me! I can see you're in that little basket up there!
