I love this. Apparently back in the day someone gave an old piece of wood to the Dutch Prime Minister and told him it was a moon rock, and the dude totally bought it.
Notice that the plaque very carefully does not actually claim the thing is a moon rock. It is merely a gift to commemorate the visit of the moon astronauts to the Netherlands. If you misunderstood and thought we were giving you a moon rock, well, that’s your own damn problem, Dutch boy!
