Aha, now at last it comes out:
A treasured piece at the Dutch national museum - a supposed moon rock from the first manned lunar landing - is nothing more than petrified wood. At one point it was insured for around $500,000 (£308,000), but tests have proved it was not the genuine article.
The US agency gave moon rocks to more than 100 countries following lunar missions in the 1970s. US officials said they had no explanation for the Dutch discovery.
I have an explanation - they didn't go and it is moonbattery to say they did. The science itself precludes it and now, the last major argument that they did has fallen away.
Watch the proponents of the moon landing say it was only a one off hoax in Holland and that all the other bits of moon rock are genuine though. :)
