It was a beautiful day for a Christmas parade in Richmond, Va. Happy crowds lined the streets as Santa's helpers passed out candy and the marching bands played. Onlookers cheered as the star of the show, a giant inflatable Rudolph the Reindeer balloon, made his way down the street.

But then, tragedy struck.

You know what's going to happen and you know it won't be pretty. And yet, you just cannot look away.

Parents, you may want to send the kids out of the room for this one.
