If you ever want to be on the Olympics with a few seconds of TV coverage, here's how you might be able to pull it off.  The reason I say 'might' is because they might not be allowing people in this area post-9/11.  I noticed this while watching the '84 Olympics in L.A.

One of the equestrian events is some kind of 'long distance' race and the horse and rider go galloping off along a long winding track.  In a few of those places are cameras to catch the non-stop action.  Apparently, spectators can walk right up to the fence on the outreaches of the track and watch the horses go by.

In a few of those spots you can get within the camera's range and just hang out on international TV for five seconds as the horse goes galloping past.  These are fixed cameras, as I recall.

You'd have a tiny monitor TV so you could tell when the camera was on you.  Casually give the camera your studied pose, chin proudly tilted up, hair blowing in the wind, the sun in your eagle eyes.  On the last day, on the final shot, hold up a big placard that says "FOR A GOOD TIME CALL…" and then your phone number.  You might inundated!

I'd add that I'm not sure if anyone has ever done this routine on purpose, in the sense that the people I saw appeared to have no idea they were on camera.
