Mo,

When you're taking your shower just make sure there's not some hairy guy in there with those stupid Vikings horns on his head.

But speaking of rooting for an historical enemy because it may benefit you, Winston Churchill was grilled on the floor of the House of Commons for his support of Stalin to help defeat Hitler to which his laconic reply came, "If Hitler invaded hell I would make at least a favourable reference to the devil in the House of Commons."

Sometimes you root for the devil. And it doesn't make you bad.
