This is told to me by a Danish classmate (while intoxicated at a party).

He asked me: do you know why we say "Skull" when we drink? I said: No I don't.

He Said: Well, back then during the Viking times. The Danes would fight all the way to the kingdom and cut the off the Skulls of the English princes; Dump out their brains and use the skull as cup for drinks. Hence the word "Skull".

I said: Huh? Interesting!

"And then we also took all their good looking women. And that's why all the Danish girls are soo good looking" Add him.

You got love the Danish people!
