Passed on from someone in the office.
READ THIS BEFORE WATCHING:
> This is a car advertisement from somewhere, looks like maybe Europe.
> When they finished filming the attached commercial, the ad people who
> made it noticed something moving along the side of the car, like a
> ghostly white mist.
>
> There was also an eerie sound which could be heard. The ad was never
> put on TV because of the unexplained ghostly phenomenon.
>
> When you watch it, pay close attention as the car goes behind the hill
> and tree and you'll see the white mist crossing in front of the car
> then following it along the road. If you have your speakers turned up you can
> actually make out the eerie sound.
