Introductory Movie on First Boot ????

Please forgive me if this question has already been answered.

I just bought a 20" iMac for my dad for Christmas. Of course I couldn't help but open the box when it came in the mail yesterday to gawk at its beauty. The problem here is that I want to fire up the machine to do some tweaking and install some widgets and other apps, but I would like for my dad to get to see the "movie" that plays when you boot up tiger for the first time. This will be his first Mac, he is very excited, and I don't want to blow that experience for him (lame as that may sound). Is there a way, or a script that I can run, to tell the machine to run that movie again on the next boot up, as if it was the first boot? I've searched all around the forum here and the only thing that I could find is the location of the movie on the hard drive. Also, the movie itself and the audio that goes with it are two seperate files. Thanks for the consideration.
