Two Norwegian jokes I heard recently and don't want to keep myself from inflicting on all y'all:
A Norwegian, a Dane and a Swede made a bet who could endure the stench of a pig sty the longest. They all entered together.
After two minutes, the Dane came running out.
After five minutes, the Norwegian came tumbling out.
After ten minutes, all the pigs came running out.
Q: How do you recognize an extroverted Norwegian?
A: He's looking at your shoes rather than his.
