To commemorate our landing, here is a rock.

This week the Dutch National Museum discovered that what they had been given by the United States during a goodwill moon landing tour was really a petrified piece of wood, instead of what's always been known to be a moon rock.

I really don't know what to make of this one, but here are the choices:

a. The US never wanted to give a moon rock to the Dutch so they gave them a fake hoping they will never notice.

b. There is wood on the moon.

c. No moon landing ever happened, ergo no moon rocks. ( I know I'm going to get emails on this one).

d. Packaging error.

Occam's Razor says that I should pick the simplest one, so (b) it is!!!!
