Suggestions, please? I need revenge for a practical joke!

My dad got me good in an e-mail. I need to get him back.

First, here is the e-mail he sent me:

From the "How did we ever live before we had email" department.

WARNING - NOT FOR KIDS!!

Subject: Spooky Car Commercial - READ MESSAGE FIRST

This is a car advertisement from somewhere. When they finished filming the
ad the people who made it noticed something moving along the side of the
car, like a ghostly white mist, and an eerie sound that you can barely hear
( must have sound).The ad was never put on TV because of the unexplained
phenomenon. Watch it and about halfway through, you will see the white mist
crossing in front of the car then following it along the road ...

I almost did not catch it the first time. Turn the volume up and look close
as the car passes behind the tree! It IS very weird!!

Attached was a file that I managed to find a link to online, so you can actually see what I saw (WARNING: don't do this late at night, especially if you are alone, because even if you do not believe in ghosts or are not afraid of them...trust me, you will get a shock :) (also, my attempts to make this into a link have made only weirdness...you'll need to cut and paste. Sorry...)

Heeh...now you understand! Sorry if you fell for it :)

I DID read this late at night, while everyone else was in bed (against my better judgment). This was ten minutes ago, and my adrenaline is STILL racing. So I sent him an e-mail saying I would get him back. But I need ideas. My "you are an idiot" link is not quite right. (Plus I would never call my dad an idiot. This was brilliant, really, even if he did not make it up himself.)

As soon as I figure something good out, I will wait a few weeks, maybe send him some normal links in the meantime, give him a chance to let down his guard. But I need something to get him back.

Suggestions? Please, nothing R- or X-rated.
