Righteous, thought the millions of people who have already seen this one. In fact it was sent to me by a non-IotD reader -- there are still a few left.
It's NBC reporter Meghan Stapleton, doing a holiday bit from North Pole, Alaska, and young reindeer Blitzen apparently had enough and jumped her. She wasn't hurt, and in fact she held onto the lead and stopped Blitzen from running away.
You just know she flew all the way there just to put on 30 seconds of holiday "cheer" for "news" watchers. But the delight and good will the world will have upon seeing this will surely be greater than that she would have generated with the piece.
