Danes and Vikings, plus: Two words to use to get Danish people to do what you want

I play a little game sometime when I look at Danish people. I imagine them as Vikings. It’s easy now that big beards are in fashion on young men. Sometimes on the metro I’ll look up at the hipster guy playing with his iPhone next to me and imagine him wearing a big fur cloak. Maybe a rope belt, with a sword dangling from it. I imagine him stepping off the boat in Newfoundland in the year 1000, freaking out the local American Indians.
