On a more sober note, this past Wednesday April 24th on channel 10 in Israel the Colbotek show is airing a story about the rampant fraud in olive oil in Israel. Some olive oil that's bottled and used in restaurants is actually some kind of oil that is not suitable for eating!
The segment is available for viewing (for now) on the internet. It's a bit overdramatic, but makes the point. Now we see if someone does something about the problem.
