Sang to by Santa

Santa lives at the Hartvig's place, on a shelf in their entrance. He's a short, fat guy with a big beard. When we were there to visit on Monday night (to celebrate Nils' 10th birthday a few days early), Santa sang to me. And danced.
Is this the person they say will come visit on Christmas Eve? If so, I'm not sure I want it to happen. That loud Jingle Bells voice and those wagging hips were really both awkward and a bit scary! Santa! Stay with the Hartvigs!
